Thanks for your query.
The symptoms you have are typically seen due to Neuropathy or due to nerve
infringement.Repeated surgeries could have caused a anatomical defect which could be pinching the nerve.This causes the symptoms like numbness
, pins and needles .
Do consult a neurologist
to localize the site of involvement along the course of the nerve involved.
There may be need for reexploration surgery.
Wish you good health.
