Reading your symptoms sounds so familiar, especially the crawling ants thing. Have they offered you anything like Gabapentin or Pregablin? I really hope the tests reveal the cause so you can move forward; however, be prepared for the 'all normal' response too. I had to fight back tears when I heard this - not tears of joy, but tears of sheer exhaustion and frustration. I couldn't accept how I could feel as I did, with such physical symptoms, yet be told all was 'normal'. No, it's not normal to be turning into a human vibrator! For me, it was sheer luck that a neurologist said test estrogen as well as FSH (which was normal). In general, estrogen tests are not helpful, but for me this was the break through I needed. Really, really hope you get some answers soon. Big hugs x x
