Hi Jean, I have a similar nerve issue in my left thigh. It did not come from my kidney donation, but from an unrelated abdominal surgery last August. The 'shocks' and pain stopped, but the numbness is the same after 3 months. It affects the upper front of my thigh to the edge of my pubic area.
So I discussed this with a good friend who is an anesthesiologist. It is called Meralgia paresthetica and is caused by compression of the nerve from the body position during long surgery. *Fortunately* this is a sensory not a motor problem. Steve told me it may go away over the next year, or may well be a permanent problem. He did say I'd get used to it...not terribly comforting, but true.
I should think your abdominal pain is not due to the nerve compression, but to the surgery which was only six weeks ago. I found that getting back into my workouts (I run and lift weights) actually helped resolve my pain. Gentle stretching helped too - I suppose it eased up the tightness from scarring.
If your pain is very bad, if you have motor problems, or fever you really need to get medical attention. You said 'pretty severe' - in my mind, severe pain requires medical care and maybe a trip to the ER. I'd say at six weeks out my abdominal pain when I was tired at the end of the work day was a 4 or 5 out of 10. Irritating, but I wasn't calling 911, just taking Tylenol and trying to get some rest.
Love, elephant
