My first visit to my GP was because both of my feet and legs went completely numb below the knees and my arms and hands had limited sensation below the elbows. I thought that I may have pinched nerves because it came on within 1 week. Years of testing for MS, ALS, CIDP, and brain tumors were negative, so then it was "in my head" despite frequent falls, foot drop and extensive damages shown on EMG. I did not get a Lymes diagnosis until almost 4 years after the onset of symptoms and have had it now for 11 years. I have relapses that further destroy my nervous system, no cure is known and so far no treatment has been helpful. My suggestion to is pursue a diagnosis and get the labs and studies to back up your symptoms because if the MD doesn't know what it is, they may blow you off until it is too late to reverse the damage (like in my case). Good Luck!
