Long COVID: A sensation on your skin can linger on for months

The coronavirus pandemic shook the whole world – a virus that transmits too easily and is potentially fatal as well with a plethora of mutations has left medical health experts in a dilemma on how it should be managed. Although a number of pharmaceutical giants have rolled out their respective vaccines to combat COVID-19, there continue to be concerns around the infection basis its severity, symptoms, and duration. While some patients recover from COVID easily without severe symptoms, there are a few who struggle with long COVID and prolonged side effects, weakness, and brain fog.

Several studies since the pandemic’s start have linked post-COVID complications to a high risk of heart diseases, vasculitis, and others. However, when a patient struggles with long COVID, there is a particular sensation that may linger on your skin for months.

Can long COVID give skin complications?

Several people who struggle with long COVID complain of a strange tingling sensation on the skin even after recovery. Besides tingling, patients also report numbness and prickling if sitting in the same position for too long. These are known as paresthesia triggered by excessive pressure on the nerves that supply blood to limbs. This goes away once you start moving; however, if suffering from long COVID, the symptoms may linger on for longer.

What are the symptoms of long COVID?

Patients who have struggled with or are struggling with long COVID are likely to experience the following symptoms:

1. Loss of smell and taste
2. Brain fog
3. Shortness of breath

Recent studies also show that long COVID can make an individual more prone to vasculitis, nerve-related issues, strokes, and even a heart attack. Earlier, the World Health Organisation (WHO) stressed how long COVID can affect all body parts.

COVID is assumed to be an upper respiratory disease; however, it is a systemic infection that may attack the heart over time. Meanwhile, health bodies stressed getting vaccinated as soon as possible to lower chances of long COVID, the same can also be effective in managing post-infection complications. The symptoms may resolve over time, yet, the related heart struggles need to be dealt with better, and worldwide there has been stress on the immunising shot for that purpose.

7 causes of burning sensation in the feet that you should know

A burning sensation in the feet is a common clinical symptom of several conditions affecting people of all age groups. It can be short-term or long-term and often comes along with redness, swelling and increased feet temperature. Usually, these associated symptoms help identify the underlying cause of the condition. Although general fatigue and over-exertion are the most common causes of burning feet, here are some of its serious implications that should not be ignored.
 
1. Peripheral neuropathy: It is a condition in which peripheral nerves that transmit signals from the brain to the limbs get damaged. As a result, they transmit the signals of pain without any injury. Peripheral neuropathy is common in people with diabetes. It is an indication of diabetic complications due to poor blood sugar control.

2. Vitamin B12 deficiency: Vitamin B12 plays an important role in several processes of the body, including those involved in the functioning of the nervous system. Therefore, a deficiency of B12 can cause burning feet along with a tingling, burning sensation in the arms.  

3.Hypothyroidism: A low level of thyroid hormones can cause all the processes in the body to slow down. When the extremities do not receive a normal flow of blood, swelling due to water retention may occur. This accumulated fluid exerts extra pressure on the nerves causing pain and burning sensation in the feet.

4. Vasculitis: At times, blood circulation may get affected due to inflammation of the blood vessels, also called vasculitis. In this condition, the immune system attacks the blood vessels and causes inflammation.

5. Hypertension: Another condition related to blood circulation that can cause burning feet is high blood pressure. Hypertension can also cause decreased circulation resulting in changes in skin colour, reduced pulse rate in the feet and reduced temperature in the extremities along with a burning sensation.

6. Toxin accumulation: Too much of anything can be harmful for health. This especially holds true for drugs and supplements. An overdose of vitamin supplements (mainly vitamin B6) or heavy metal poisoning can damage the peripheral nerves and blood vessels to cause pain and swelling in the feet.

7. Infectious diseases: Although burning feet may not be a key symptom for infectious diseases, they too can cause neuropathy. Some of diseases in which feet problems may occur include HIV/ AIDS, Lyme disease and Guillain-Barre syndrome.

That feeling of numbness in your feet and toes can be caused by a variety of conditions. Numbness is often accompanied by a tingling feeling. The cause may not be serious - it can be as uncomplicated as paresthesia (your foot 'falling asleep'), however it my be as serious as diabetes, multiple sclerosis, or a symptom of a much more serious condition. Whatever the cause may be, it is essential to address the numbness in your feet. Avoiding to do so may affect your ability to walk.

Typical causes of numbness Numbness of the toes generally occurs due to conditions that affect the nerves or blood vessels to the foot. Most common causes of toe numbness include: Compressed nerves of the foot from footwear Injury to the foot Nerve damage (also known as neuropathy) Poor blood circulation to the foot, usually due to diabetes and peripheral vascular disease Irritation of nerves in the lower back (possibly due to a herniated disk) Frostbite Stroke Multiple sclerosis Vasculitis (inflammation of the blood vessels) Once you and your doctor have identified what is causing the numbness in your toes, here's how you may go about resolving the issue:

Method 1: Dealing with occasional numbness 1. Exercise

Sitting or standing in one place for a long time may cause numbness. To counteract the problem, stimulate circulation in the foot by moving around. A short walk, or moving your foot as you are sitting down, will help too. In addition, bear in mind the following: To begin with, regular exercise can help prevent numbness. So be sure to incorporate physical activity into your daily schedule. If high impact exercises, such as jogging, causes numbness in the feet and toes, try lower impact exercises, such as swimming or cycling. Before you start your workout, be sure to stretch well, wear appropriate shoes and exercise on level surfaces.

2. Change positions

Certain sitting positions may cause numbness in your feet. Avoid sitting on your feet or crossing your legs for a long period of time. Should you sit for long hours, elevate your feet periodically to increase the blood flow.

3. Avoid wearing excessively tight clothing

Pants, socks or other tight garments worn on the lower part of the body might restrict blood flow to the feet, causing numbness.

4. Massage the foot

Massaging the area of the foot that feels numb will help increase circulation and reduce the effects of occasional numbness.

5. Keep your feet warm

The cold may cause numbness and tingling. Reduce the effects by staying warm with a heating pad or heated blanket.

6. Wear the right shoes

High heels or shoes that pinch the toes may cause numbness in the feet. This may also arise from wearing shoes that are too small for you, especially while exercising. Opt for comfortable shoes that fit you well.

7. Book an appointment with your doctor

While occasional numbness in the feet or toes caused by an uncomfortable seating position or tight clothing is nothing to worry about, a visit to the doctor is essential if it occurs frequently or lasts for more than just a few minutes. Be sure to seek emergency treatment if your foot numbness is accompanied by symptoms such as weakness, paralysis, loss of bladder or bowel control, or slurring of speech. Pregnancy may also cause swelling in the feet and toes, which could result in numbness. In this case, be sure to follow your doctor's recommendations for relief of occasional numbness.

Method 2: Dealing with Numbness Related to Diabetes 1. Get a diagnosis

Chronic numbness in the feet and toes is often due to diabetes. The feeling of numbness occurs because it damages both the nerves and causes poor circulation in the feet. Numbness is usually one of the first symptoms of diabetes, so be sure to get tested immediately. It can be extremely serious for a diabetic, as they may not be able to feel pain, which may be caused by heat, punctures or blisters in the feet. In addition, due to the restriction of blood to the feet, diabetics' feet heal at a slower pace. Consequently, infection is a serious concern.

2. Manage your diabetes

The best way to prevent circulation issues and neuropathy is to keep your blood glucose levels in check. Here are some ways to go about it: Check your blood sugar levels regularly. While the numbness in your feet may make it difficult to exercise, try to stay active. Aim for 30 minutes of exercise each day. Eat well. Opt for a healthy, balanced diet that includes fruits, vegetables, whole grains, beans, fish and low-fat dairy. Avoid food that triggers blood sugar spikes - primarily anything sweet. Take your prescribed medicine and insulin regularly. Smoking can make the symptoms of your diabetes worse. Ask your doctor how best to go about quitting.

3. Lose weight

Obesity can be a contributing factor to numbness in the feet and toes. Consequently, losing weight will help alleviate the symptoms. In addition, it may also help lower blood pressure (which may also have an effect on the numbness).

4. Use products designed for diabetic foot care

Compression hose and socks help stimulate circulation, thereby decreasing numbness. Special lotions that contain capsaicin, may also be applied in order to relieve the numbness.

5. Ask your doctor about alternative treatments

If nothing else seems to work, studies have shown positive results on relaxation techniques and biofeedback treatments, as well as anodyne therapy (a painkilling drug or medicine).

Method 3: Dealing with chronic numbness, caused by other conditions 1. Get treatment for injuries

Numbness can occur as a result of injuries to the feet, toes, ankles, head or spine. In which case, an orthopedist, neurologist or chiropractor may help treat the injury and relieve the numbness.

2. Discuss any medications you are taking with your doctor

Numbness may also be caused by chemotherapy drugs and many other prescription drugs. If you experience numbness after starting a new medication, discuss the effects with your doctor. On this note, it is important to never stop taking your medication without talking to your doctor first.

3. Take vitamin supplements

Numbness may also be caused by a lack of vitamin B12 or other vitamins. In order to check your vitamin deficiencies, get a blood test and start taking the recommended supplements if need be.

4. Take medication for chronic conditions

Numbness in your feet and toes may also be a symptom of a number of underlying conditions, including multiple sclerosis, arthritis, Lyme disease and more. In which case, it is important that you treat and take medication for the underlying condition.

5. Reduce your alcohol consumption

A numbing sensation in the limbs, particularly the feet and toes, may also be caused by heavy alcohol consumption.
