I have an unexplained medical question. About 2 years ago, I was bitten by something (spider, I think) and my Left hand swelled up. The swelling has not gone down. Do you have any medical knowledge of what might be the cause? Are there any different tests that I should request? More information is listed below.

Lime Disease is possible.
~Spider hmm…. Do you have any new superpowers recently?

This happened to me some years ago- you can get bitten by alot of mystery creatures here- you’ll probably never know. My guess is they’ll test you for autoimmune disease, if they haven’t already. It’s frustrating, I know.

I would ask that the doctor recommend some insect bite specialists for your area (or for whatever area you were in when this occurred). Family practice doctors are not always as well informed about insect and arachnid toxins as they might be.

If it were me I would take a stab at trying an antibiotic. Pills not topical. Something like Omnicef or another that treats things like cellulitis. Or, maybe the Lyme disease drugs. I have had more than one occassion where antibiotics worked when supposedly they shouldn’t, the problem is guessing which antibiotic is right is a shot in the dark. Two times when antibiotics miraculously cured something for me I had been prescribed the antibiotic for something completely unrelated and a long standing issue I had got better. I have had situations where I tried antibiotics for something and the drug did nothing, but later found an antibiotic that helped. Shot in the dark, but I would try it at this point.

My guess is some mild cellulitis associated with Lymes Disease. Cellulitis treatment (oral antibiotics) will not treat Lymes and that must be treated separately. Get thee to a professional.

MRSA can appear as a spider bite. I assume you have seen a doctor. Maybe you should see a specialist.
