“What doctor should I see?”

What doctor should I see for an allergic reaction to amoxicillin? My knee swelled up and it's very stiff and painful. It swelled up then the pain began. After 6 months or so I was wearing a compression brace which helped it for quite a while. Then it spread all over my body, every joint was stiff eventually swelling my other or right knee, now that one is swollen. My calf tingles and my feet are stiff. When I wear the brace I also got acute abdominal pain, sensitivity to food. That happened, took a long time to figure out after I began using Blue Emu with the brace. The swelling went down, but it moved into my abdomen. When I don't wear the brace I gained back the 30 pounds able to eat non-inflammatory food again.

I had this before, ortho's only want to do surgery and they did finding nothing wrong. I didn't know it was from amoxicillin back then but just having the surgery helped it, it was fine 6 months after surgery until I took amoxicillin again for the same reason, wisdom teeth. Maybe inject saline while removing all fluid to flush the knee out?
