Hi I developed this at 28 too and now 30. I understand your fears and feelings and can relate. Try to stay in the moment though very hard but things can get better. Have you had other health conditions in the past? Dietary conditions? I know you mentioned no alchol but other abuse like drugs?Through this I have been to so many specialties I can't tell you. It is frustrating but you have to keep looking for the why and finding the right treatment. So maybe you can look into see another type of specialty doctor. I am not sure what type of doc you saw at the Miller center. I am assuming a neuro so if you have not see a reumatolgist that may be in order. Hang in there and if you want an email buddy I am here
