I had blood drawn one week ago; during the draw I felt pain and electric shock below the location of venipuncture (elbow). After blood collection, I noticed my forearm on the thumb side was completely numb. It is still numb - the area experiencing numbness is growing. The numb area appears slightly swollen, but no bruising evident. I am still experiencing shocks when I put arm down at side or attempt to pick something up (like a glass of water). I am also having a feeling like skin ripping or hair pilling in the area that appears slightly swollen (also the area that is the most numb). I went back to the doc; suggested taking NSAIDs. If not better by tomorrow, steroids. After a week should this still be getting worse? I already take Lyrica for other nerve issues related to posterior fossa decompression for arachnoid cyst/chiari malformation/syringomyelia. Quite frankly, I am surprised at the level of nerve pain I am feeling. What should I be doing?
