Hi Wiix,
Any skin condition in that location could give the sensation of being bitten.
I have eczema on ear lobes and in ear canals. I use a topical steroid cream or ointment, triamcinolone acetonide - by prescription. This keeps ears clear. It stops the itching and painful stinging sensations, as well.
A topical OTC hydrocortisone cream might help stop the itch and the peeling, if caused by eczema.
By the way, mine acts up when I eat foods to which I react or take new meds and am reacting. I can also have ears react to laundry detergent in pillow cases. I get worsened eczema or psoriasis next, if I do not stop exposure to the offending substance.
It's best to see a dermatologist to be sure of exact cause for a properly targeted treatment.
Hope you feel better soon.
Warmly,
DejaVu
