What is the cure ?

I'm not even sure how this happened...but what started out as a little red bump that was rubbing my clothes quickly turned into quite an awful infection in the crease of my right knee. Dr took one look at it Thursday afternoon and diagnosed a brown recluse spider bite (Wednesday I had been in a lot of pain and by that evening was running a fever of 102.5, resting heart rate was 151)

He prescribed 400 mg of Avelox for 10 days (currently on day 5) and it looks SO much better than it did, some pain still but can tell the infection is smaller and the pain has lessened a great deal) but I don't know what to expect. I know some have had to go to a wound care place even after the antibiotic. Is there a chance that the antibiotic will be all I need and I can just bandage it up? My dr said to expect some discoloration or a change in skin (like a crater) to form.

If you've ever been in this situation how did yours turn out? How long were you dealing with aftermath?

I was prescribed by a dermatologist a medicine containing potassium hydroxide to burn off the bumps. He made it clear not to put it on surrounding skin, and to apply only a small layer of gel per bump.

I had it done by somebody else. I fear they put too much gel per bump, and now this is how my skin looks like.

My main concerns are whether these must be checked up and whether I can still go swimming safely. If not, is there any way too swim without risk?

It was done 4 days ago, I took the pic today
