I have the very same issue, I’m 74, had TKR in October 2020 and
Developed foot neuropathy shortly thereafter. Saw two Neurologists,
had an ECG Scan which checks the nerves in legs and a deep vein
ultrasound for blood flow and no issues. Went to a uninvolved general
surgeon because I then developed a swollen lymph node in my groin,
same side as knee replacement. Had an ultrasound for that lymph and the surgeon said the ultrasound showed no abnormalities but was swollen.
He advised me that some folks with TKR do develop foot neuropathy
AND could be the cause of the swelling in the lymph node. He wants me
to wait another 6 months, if no pain or lumps etc… and have another
ultrasound completed. If no changes in 6 months, he will do a biopsy.
He said the nerves are clearly effected during a major knee surgery and could
take 2-3 yers to correct itself, if at all.
I have no discomfort with the swollen lymph node but do with foot neuropathy at night With bottom of my feet. I take a 300-milligram tablet of gabapetin at night about 6-7pm and it helps me through sleep the night.
I too was very active, did everything and this has changed my life. I’m not giving up though, will see what happens by October.
My best to you, hope this helped.
