When I was in my 20''s I had a collapsed disc. It affected my left arm/hand - I had to have traction and physio for a couple of weeks. Since then (I am now in my 40" s) I have not really had any trouble except for the odd stiff neck when I carry a heavy parcel or do something very strenous.
Two weeks ago I slipped in a puddle of water and had a fall. I was a bit stiff for a few days but it passed. Now this passed week I am having terrible pain in my left arm/wrist right down to my fingers. during the day it is fine but it wakes me during the night - my wrist is extremely sore and my fingers are totally numb with pins and needles. it takes an hour or two to come right. What do you suggest?
