Hi all,

I'm new to this forum, but I've been diagnosed with ON. The pain in the left side of my head in the back started after a root canal re-treatment of an upper molar on the left side.

I've been living with it for about a year. I tried two types of pain blocks, a couple of drugs, but I started getting more pain near my tooth. My neurologist sent me back to my endodontist (root canal doc). He started to re-treat one of the roots. My tooth pain and my ON pain increased after this re-re-treatment and I'm going to get the tooth extracted in 2 days.

Has anyone here had ON start after root canals or dental work?
