If the PET/CT rules out any concern for malignancy or infection, and if the ENT doc is unable to find any source, then seeing a Neurologist may make sense. They have some good treatments for chronic pain. With your history though, it's important to be sure that a recurrence has been ruled out.
Thank you so much for responding. I have been going through hell and worst of all, not being able to take care of my 1 & 3 year olds. I'm in so much pain that their voice levels are too much that I do not want to be around them- which kills me because I love them to death. I never thought I would feel this way. Is there any other doctor I should go see or specialist? Maybe a neurologist or allergist, I don't know. I want to exclude everything to finally conclude something. I am desperate. Any help anyone? Does anyone have any recommendations?
Your problem is clearly complex and this is why they are getting the PET/CT to help them look for a source. Hopefully that test will either ease some of your anxieties or suggest a possible source of your problem that they can investigate further. I am sorry that, so far, you have not gotten the answers you need. Medicine is not a perfect science and there is much we still have to learn.
