Tooth Extraction cased huge problem

[zanobia]

I was supposed to do dental implant, after the tooth extraction and the bone was inserted. I decided not to continue the implantation I didn't eat on the side that had the tooth extraction for 3 months and it was going fine. Then after 3 months I started eating on it normally after a while I began feeling pain in the cheek as well as the side of the nose of the extraction. This not strong pain have been there for 3 months and I started noticing that my cheek is starting to swell. I can't concentrate anymore, the problem is that the dentist have told me there is nothing that appear to be the problem.
