I had a mri on my jaw joint for bruxism. my neck muscles hurt more then the joint. ear ringing and sore. will the mri show muscle inflamation?

It can show swelling: Mri imaging in general can demonstrate soft tissue swelling better than any other imaging modality. However, other than presurgical considerations i'm not sure what the utility or necessity of an MRI of the jaw might be to simply make a diagnosis of bruxism or determine the severity of the condition.

TMJ - Jaw pain: You have a tmj/muscle dysfunction problem that is treated by a dentist. Select a dentist that routinely treats TMJ with functional orthopedic type appliances. Many dentist treat tmj, however only about 5% are really good at it partly due to familiar with a wide range of modes of therapy to better customize the treatment specifically for your conditions. Mri not very useful much of time.

Yes, but: Muscle inflammation can show as swelling, but it is clear you have a TMj problem. See a TMJ specialist. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
