Hello -question about auxiliary clearance

I had an axillary clearance along with a mastectomy. I think initial reactions can vary a lot depending on how many lymph nodes, nerve ending damage etc. I had no swelling or pain, but lost a lot of feeling. Quite a lot of the feeling has returned (over years) but I think it will always have a degree of numbness. Affects nothing except that I am not particularly sensitive to hot and cold under the affected arm. Good to keep up the exercise as it not only helps mobility but may also help prevent lymphoedema. Best wishes.
