Thanks for the reply. No I can't really get hold of it, it's in a bit of a difficult position, but from poking it it seems like it might be attached to the bone, not sure. I don't think I can feel it inside my mouth, so perhaps it's not attached to the bone?? I can't remember if I had Antibiotics when I had the root canal done to be honest, but have had several rounds since after having a swab of my mouth come back positive for Candida and Strep B. I had a round of penicillin about a month before the swab and it obviously didn't get rid of the Strep infection.
I took a massive amount of a vitamin C for a couple of weeks recently (managed to reach 50g a day without hitting bowl tolerance) but stopped because I was concerned it was making the parasites worse.
To be honest I know I've had Candida mildly for 10 years, and also a pin worm infection. I had the Mirena IUD fitted nearly 2 years ago and that's when it all spiralled, but have now had it removed. Just looking for whatever is still not allowing my immune system to function at full strength. Also have a very stressful job which I don't think helps.
