Hello, my father has had a red spot on his shin for about 3 weeks now. He tried to squeeze the infection out but ended up making it worse. Yesterday he said he saw something yellow where he had made an incision and pulled out something yellow and hard that was a cylinder shape and now he says it hurts even worse.
HIIT could be infected sebaceous cyst. Please consult your Surgeon and get examined clinically. If it is a cyst, get it removed surgically. Nothing to worry. Wish you good health. Regards
