I notice there is a white head on the tip as well. really dont know
what is it.. I have been taking antibiotics (a week) and
cetirizine (one month) and isotrotinoin (few months time) for a while. That is strange as I assume cetirizine should help anti-allergy as doctor prescribed to me when I had other allergy on my skin - it occurs when my skin have pressure on it and it goes red and itchy, when you scatch it, it swells a big piece.
