For the last week I have experienced a numbness and coldness on the out side left upper leg. The cool area seems to be real as it feels cool to the touch.
I did get a total knee replacement on that leg 1 plus years ago.
I also suffered from a lot of pain coming from that knee and hip after playing tennis. Tennis pain occurred about 6 weeks ago and the pain subsided about 3 weeks ago.
I would see a neurologist to examine for the possibility of nerve damage.
Peripheral nerve disease can evaluated with a nerve conduction study, and central causes can necessitate an MRI. It is possible that residual nerve damage can be a result from the surgery.
Metabolic causes can be evaluated with thyroid and vitamin B12 tests.
These options can be discussed in conjunction with a neurologist.
