### input:
I ve had ongoing headache , ear, and jaw pain since before a root canal/crown back in February. The jaw pain is worse since the dental work and when I went back to the oral surgeon he suggested I may have TMJ in addition to a possible neuroma on a nerve in my jaw. That was in May and he wanted to wait a few weeks. I am in constant pain, and I get some radiating soreness into my throat and neck. The last month or so my neck has been increasingly worse so I saw a chiropractor and my masseuse worked on my neck quite a bit afterwards. It feels better but is still quite tender, especially at the base of the scull at about mid-ear level. Is this pretty classic TMJ stuff? I should also note I ve been very itchy lately and not sure whether that has anything to do with it, but it is mostly on my back and upper arms, but there is no rash .

Hello and welcome to Chat Doctor forum, i would like to inform you that your oral surgeon is right when he/she says that it's a TMJ related problem, sometimes post cementation of the crown over the RCT treated tooth, TMJ problems have been noticed, this occurs due to improper cementation of crown. Or there may be a problem in the tooth itself which has undergone RCT, I would have appreciated if you would have sent in your tooth x-ray, I assume that RCT has been performed correctly. For treating TMJ problem you need to visit an oral surgeon, he/she will prescribe you muscle relaxants, and suggest you a few facial exercises. Also, itching over the area is not associated with TMJ problem.I wish you good health, take care.
