Disc displacement with reduction. TMJ.

I have constant due sore and throbbing pain for more than 2+years in the lower jaw under the ear area and the neck on the right side. Have seen several doctors and specialists without any relief/ diagnosis. Have had MRI and CT of jaw and neck. The report said normal. I saw a new OMFS and he said I might have disc displacement with reduction and Capsulitis. But the CT and MRI of tmj reports are normal. What is the recommended treatment for disc displacement with reduction? I had a tooth#46 which was hurting for tapping and biting pressure since this jaw pain started. Cbct scan of that Tooth was normal but it was painful constantly for 2+ years. So I extracted it a month ago and still have the same symptoms. Only difference is tooth out but have pain in that socket/ gums and #47 gum hurts too. I have a night guard but that doesn't help with this jaw pain. This is constant pain since day 1 and no changes even after taking Nsaids, muscle relaxers, nerve medicines etc.
