This is the second time this is happening. Have some irritation around penis tip though no irritation while urination. Last time this had happened becoz of sugar content (i was consuming cinnamon with tea). This time 2 weeks earlier I was suffering from viral fever and cough, post doctor consultation I had taken couple of medicines along with cough syrup. After consuming cough syrup dosage, this irritation around penis tip relapsed. Last time, I had started taking bitter gourd post which this irritation stopped. Kindly guide should I undergo sugar test? I have a family history of diabetes but my family members is suffering from diabetes after a certain age and it's in controlled conditions.
