Ok just an update. I was pretty sure that its TOS but the warm thigh sensations and crawling in my feet was bit worrying but physio said its just my nervous system has gone sensitive.

My MRI and blood tests came back all fine except positive ANA. I had this before but rheumy blood tests all came back negative. The gp tests now positive so I have been referred back to rheum.

Im just wondering, those of you with SFN or other autoimmine diseases do you feel any burning sensations when doing nerve glide/ tension tests? I feel as if somethings tugging on my nerves when I do these tests which is why I still believe I have nerve compression.
