Hi I am sorry you are facing this and the struggles of why. I am from MI too though now I live in FL. Have you seen any rheumatologists yet? I am glad you are getting other opinions too. Have you had any emg or mris? Sometimes one can have a multiple dx. Even on here people have auto immune and PN and each causes there own set of pain. I am not sure what the meaning of the tests are but can you call your doc and speak to him on the phone? He should tell you what the meaning behind this is. Don't be afraid to speak up it is very important. Make sure to keep copies of all your test results to bring to your apts too. I wish I could help you more but try to take 1 day at a time cause it just takes 1 doc with a new approach and eye to help you.
