There are meds in the U.S. that can relieve the tingling, but if that doesn't bother you I wouldn't bother with the medications cause you can have side effects from them. I was going to recommend them if you had the burning from the nerve damage, but since you don't I guess I won't.

I'm sorry the surgery didn't correct everything, but that's the chance we take with lumbar surgery (or any surgery for that matter. ) I'm glad you don't have any more pain. I wish my surgeries had been that successful.

Best of luck and keep healiing!!! God bless. Hugs, Lee
