I would get it looked at- nonhealing scabs can be a leading indicator of melanoma- getting tested for other tick-borne diseases would also be reassurance.

I had something like that below my eye, sore that kept scabbing over. Turned out to be basal cell carcinoma. Had it removed by a dermatologist. No problem since.

I have one of those on the left cheek of my butt. I can't see it well enough to get at it to do serious digging, or I would dig out whatever is in there. It has bugged me now for about a year and a half. It will almost heal and then get irritated and itchy all over again. I'm sure it is an imbedded tick or tick head. I have tried the knife tip but can't see and manipulate enough to get it done. Girlfriend doesn't want to operate on it either.
