I’ve gotten two infections post op.

Got my wisdom teeth out memorial day weekend. Was prescribed 5 days amoxicillin. All was well, until about a week after when I started having some discomfort in my bottom right side. Went back to the surgeon, he wasn’t sure if it was an infection but prescribed antibiotics anyway and took the stitch out. it started feeling better when the stitch was taken out, but when I started the new antibiotics (amoxicillin + kclav) I developed hives so I stopped the medication with the surgeons direction. I only took about 3 doses. Everything was fine until about two weeks ago when pus starting coming out and there was a giant lump, still in the same tooth. Was prescribed a 10 day course of amoxicillin. Took that, everything was fine. Now, I am having pus coming out of the OTHER lower side. What is happening??

I have done everything, irrigated, taken antibiotics as prescribed, I don’t smoke or vape, I have good dental hygiene. The two times I have gotten the infection I had a cold before hand, so maybe that has something to do with it? Someone HELP ME!
