Hi,
for the past six months or so i've been experiencing semi regular sudden numbness or shocking feelings in a variety of limbs. These will happen when i'm waking up in the middle of the night, usually there accompanied by a few seconds of blurred vision, and eventually all symptoms would go away. For the longest time they would only occur in my arms or legs, but recently I had the strongest of the attacks, it was in my chest and shoulders and was much stronger than ever. Of course since it was in my chest I went to the ER and they cleared me of any heart related problems, they did blood tests and cleared me of any thyroid of diabetes problems. Before this episode i was prescribed xanax because my doctor thought it might be stress related, while it did seem to help, these new stronger symptoms have not been effected by the xanax at all, and since the initial attack have been occuring much more frequently.
any ideas? i've search about everything with no luck
