Hi, I got something similar, after my 12/05 revision of TKR. Oh boy, so i started with Rheumatologist sending me to Nuerologist for nerve testing-EMG, and did that hurt, the needle probe on bottom of numb foot
It was pretty painful, the nueropathy, ball of foot, so i took a lot of Darvocet, i had to go to a Sports store and buy mens wool socks, because they were loose, and anything touching my foot, hurt. especially socks, it was winter!
...So after the Nuerogist, i took the reports to my ankle/ortho dr. who fused my feet, and he ruled out Tarsal Tunnel Syndrome, and ruled out anything footwise
Then i moved on to ortho/spine specialist, because i suspected the nueropathy on that operated TKR revision, came from the back. And i found out i have stenosis, and other things, (had MRI'S), epidurals, Therapy.
I started with Nuerontin (Gabapentin), and am now on Lyrica 75 mg only at night.
So, after 4 years, it's stil there, they call it diffuse periphael nuropathy(non diabetic)....and if i skip a dose of Lyrica, the foot will really feel more numb
Sorry, this is so lengthy..I am getting a TKR revision, end of next month, and am worried this will happen to my other foot. I am not ready for a back fusion, so there are definate back probs.
When this all happened, it seemed the nuerologist blamed it on ortho/ankle surgeon, who then blamed it on knee guy, and i don't even remember how i ended up at back doctors at this point.
My ankle surgeon is very prominent, and it's a 2 to 3 month wait, and i doubt there will be a cancellation. So i have an appt with another ankle surgeon/ortho..on 8/17th, not as prominent, but he would know the doctor that is doing knee revision.
I want to ask him, is there something about my foot, back issues they need to be aware of, before they revise my knee.
I know i had to elevate my leg a lot after the revision, so it seemed to aggravate my back probs, and i am probably never going to know why the numbness happened, it's still there, but not as bad
