During my last flare i woke one moring to find that my left arm was numb, i thought that perhaps i had slept on it but it did not get better when i moved around and i could move it, but it was weaker and numb! the sensation gradually started improving but i did have some burnig pain in my had for a while- i have been left with mild sensory loss in part of my left hand and i can't lift my arm above shoulder height anymore but i am working on some physio to see if i can get the movement back (or at least prevent a frozen shoulder)
