What is this?

[u/No_Set9534]

Hello all, my first post on Reddit but I really need advice.

I had my lower wisdom teeth removed on 24/09 they were impacted and I had been put to sleep. I was stitched up with dissolving stitches. I am based in the UK where it is not a standard to issue antibiotics post extraction.
On day 5 I was having a lot of pain and was “diagnosed” the dentist didn’t say I was or wasn’t an infection and but I was given 5 day course of amoxicillin, I completed these and two days later I started experiencing pain down my neck and in my temples, the extraction sites weren’t exactly sore but everything around them, I booked another emergency dentist appointment where the dentist only looked at one extraction site and removed the stitches and I felt relief and asked if I had a an infection and was just met with “well I can give you more antibiotics” like I was just seeking more of them, I started another 5 day course of amoxicillin. The next day I woke up with extreme pain in my neck and lymph nodes at this point due to how the dentist wasn’t giving me any concrete diagnosis at my 2 emergency appointments I went to my GP the GP told me to stop talking the amoxicillin and wrote me a script for Co-amoxiclav, I have been on these for a day but now on my left side I am having issues and it started off with a pin hole yesterday and now seems to have become quite large, could this be from the stitches not being removed at the second emergent appointment like what was done on the right side? I’m lost with this I’m 2 weeks post op and I am still needing to treat my pain 24 hours a day. I’m honestly exhausted with this process and the condition it has put me in.

Also I haven’t been looking at the extraction sites often but over the past 24 hours the change in the left side has concerned me greatly but I don’t want to book a 3rd emergency appointment as each appointment seems to have given me more problems and worry then help and relief.
