7 Instances a Cold Warrants a Doctor's Visit

Normally it is said that for cold whether you take treatment or not, it will go away on its own in a week. But, that doesn't mean all colds are the same, for some, we do need to take extra precaution.

It has been more than 3 weeks
Three weeks may sound like a long time. Though it is highly normal for a cold to last up to 21 days. Coughs that last more than three weeks however, are more of a concern. Prolonged symptoms could be signs of asthma, pneumonia or a different type of lung pathology.
 
Your symptoms are back and worse than before 
There are times when you begin to feel better, but only rebound and get much worse. There are some emergency signs that require immediate medical care. Usually, flu-like symptoms that seem to improve but return with a worse fever and a cough warrants a visit to your GP. It's possible that you may have a secondary infection, which could be anything from bronchitis to pneumonia. 

Your phlegm is of a strange colour
Thickened saliva is common in a cold, but phlegm that is a strange color signifies that something weird is going on in your body. Colors like yellow, brown, green or even blood, are of concern.  

Your eyes are itchy or watery
Tearing up nonstop? Unless there's a pet in sight, there's a chance you may have allergies rather than a common cold. Though at times, it may be hard to tell the difference. There are more than a hundred strains of cold viruses, each of which tends to become widespread at certain times of the year, which is why you may think that you have a cold, rather than seasonal allergy. Hives, tongue swelling, feeling lightheaded, stomach cramps and more indicate allergies.  

You're losing weight
Unexplained weight loss (i.e. you're eating normally, but still losing weight), coupled with cold-like symptoms could indicate hyperthyroidism, cancer, a bacterial infection or even HIV.  

You're wheezing
Coughing that is accompanied by wheezing or chest tightness may signify an asthma attack. During which, your airway linings swell and become inflamed, get clogged by mucus and then becomes constricted due to tightening muscles. As a result, breathing becomes difficult. If you experience any of these symptoms, speak to your doctor.  

You feel a lot of pressure
Be wary if you're experiencing pain or pressure in one specific part of your body. Strep throat will cause pain in your throat, while pain your nasal passages may be due to a sinus infection. Ear infections, however, accompanied with hearing loss, severe pain in the ear, or any kind of discharge coming out are reasons to visit a doctor.
