Hello

I fell over 6 weeks ago and a glass went into my left elbow, damaging 50% of the median nerve and 3 muscles and 100% of a  muscle.  I had a plaster cast for 4 weeks but since then no feeling in my middle finger and my forearm and excruciating pain in my wrist. I have like permenant electric shocks that go right down to my finger tips. My doctor also thinks I have Complex Regional Pain Syndrome. Any ideas on how long it will take me to recover?
