Hello germ. Welcome to the forum.
My ulnar nerve injury was not from a blood draw. I had a transposition done and now have a 'limb alert'...NO Venipuncture on the left arm, as my nerve is now in a different location.
I'm sorry to hear of the trouble you are having. I am one of 'those' that has the numb, burning, tingling sensation 24/7. I guess I've become accustomed to it as I hardly notice it much anymore. It's no where near as 'strong' as it used to be. Nerves take their time healing. There are medications that can help calm them down.
I also experienced a poorly placed Demerol injection that affected my sciatic nerve several years ago. The pain was indescribable! The memories are a bit fuzzy at this point, but I recall it was only a couple of months before it calmed down.
Hope your situation resolves quickly.
