Question: I keep getting large inflamed sores on my chin that won't heal and itch horribly (unlike acne, there is no single white head). It will ooze fluid and scab over with a scab that is 3/8th of an inch and when the scab peels off it feels like a burn, very raw pain. Then it repeats (itching, oozing, scab, peeling, soreness).

I have a goatee. I don't know if that makes any difference. At time I get this crawly feeling and the sores and the skin around it starts to itch really bad.

My dermatologist took a biopsy to test for cancer (I did have a small basal cell carcinoma behind my ear, though it was just a bump. The symptoms were not the same). It came back negative.

I was prescribed Doxycycline Hyclate 100mg for 10 days. I took and finished the prescription and it had no noticeable affect. I also was applying Mupirocin 2% ointment, again, it had no affect and seemed to aggravate the sores.

My dermatologist injected the larger sores with Cortisone which did cause them to shrink but a new ones appeared. I think the shots treat the symptoms (inflammation) but not the underlying cause.

Recently I've been on Monocycline 100mg once a day and I've been applying Cloderm cream twice a day. Nothing seems to be working and the sores are spreading and getting bigger.

Could this be a fungal infection? If its bacterial, is there a stronger anti biotic that I should be taking?
