### input:
hello. I am a 33 yr old male with chronic neck/jaw pain. i weigh 155 lb and am 58. The Pain has been present going on 4 yrs now and seems to be getting worse..ie ear pressure and constant popping. All this only on Rt side. I have seen dentists, tmj specialist(i wear a mouthgaurd every night), 3 ENTs, and physical therapy and am now seeing a neurologist. I have had 2 CT scans and multiple scopes of neck. All have come back with no result/or answer to explain this pain. My neurologist just had a stellate nerve block performed with little result(did feel a little relief), last week and thinks that i should have another one performed ASAP. stating that the effect is greater the more you have(limit 4)? I guess my question is that i am unable to get over the fear that they are missing something in the CT? is this a possibility? Should i inquire about having an MRI? is there any difference?FYI..I also smoke marijuana before bed--lightly

Hello, You have been very thorough and utilized specialist which would be my first recommendation. I would continue with the treatment recommended by the neurologist that offered relief and hope for benefit with the cumulative effect with multiple treatments. The MRI is utilized in evaluating soft tissue and is a very valuable diagnostic test. Contrast medium can show details on vascular components which may assist your diagnosis. You may have an autoimmune component or have a multiple condition syn Chat Doctor.  I suggest checking on your family history and look for any genetic disorders that could help with diagnosing. You may consider anti-inflammatory medications and muscle relaxers for temporary relief. Ask your doctor for suitable prescriptions. Thank you for your inquiry. I hope my suggestions offer relief and further guidance. I am available to answer additional questions.
