Sir, this pimple has been a recurring thing on the same spot. It is i believe there since approx 4-5 months and has become pus filled 2 or 3 times. The previous pus oozed out itself but the spot remained dark, hard and swelled and felt pricky kinds. Now again it has become like this. What could be the reason and what ointment or Medicine should i apply. Also any home remedies that can help. We wipe his face after meals and he does not eat much of oily foods.
