What should I do? Should I go to a doctor if my keloid is infected? Will my whole leg be? Will the skin grow back? (photo)

Hello,Apart from the panel members suggestions, you should seek medical attention to address the signs and symptoms of injection before considering a cosmetic option.  Please make an appointment with your primary care physician soon.  Green drainage, swelling, and bleeding need attention.

I recommend getting a formal evaluation with a cosmetic dermatologist for after care and treatment. I don't recommend trying to remove keloids yourself. Keloids can be improved with lasers, microneedling/prp, 5/FU steroids. Surgery with or without radiation is an alternative. See an expert. Best, Dr. Emer

Dear mj831,it is hard to tell without an examination. I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS

Surgical removal followed by Kenalog IIT and Plato's scar serum are excellent options for your keloids. Best, Dr. Karamanoukian#Realself100 Surgeon
