Despite having no obvious sign of infection around it, I been sick from
the day I got a dental implant (lower back molar).

that spot had had a long infection brewing before the tooth was
removed. the tooth was out for a year and then they put an implant.
Since then I have felt exactly the way i did when I had the infection.
There is a slight swelling in the area but it is not blown up.

Has anyone else had an immune type reaction like this to a dental
implant?
