Hello Dear,
The altered sensation you experience may be due to the denervation as sensory nerves get affected in the operation and their healing might take some time.It is a normal phenomenon and do not worry.
You can consult your doctor about this and take care.
Best
Thanks.. I had the surgeries years ago... the one was 1985 and the other was 2001! I am just concerned because its tender/achy and of course like I said I get this feeling like someone is pulling stitches out of me... I will ask my Doctor when I go see her soon.
