42 years male from india have a keloid on chest for last 25+ years. Last november I got some pus in keloid and its healed on its own. Again in december got infection in mid of the keloid that with pus and sore. I visited dermatologist and he prescribed me ceroxim 500 tab bd for 10 days and mb rock (mupicropin) ointment for 15 days. The infection, pain was cleared. Again 6 days ago the keloid certainly became red, itchy and got an infection with pus and sore. This time I noticed a hair coming out of the sore. Every morning pus coming out from the sore or nearby area within the keloid. Please help me to get rid of this.
