@josie1957 it hasn’t been very long yet so maybe he is right and it will resolve. I hear from others on here with post-TKR problems that they are told to give it a year.
If/when you feel an unreasonable amount of time has passed you should consider a second opinion from a doctor at a different medical center. I know it must be difficult to wait but you do need to try to be patient and hopefully it will go away either gradually or, as in my case when I had pain, almost overnight! .As I mentioned previously I do have some very minor numbness after water jogging for a long time. When I get that it goes away fairly quickly.
Please let us know how you are doing and if the numbness starts to decrease. I am not a medical person at all, but I think it might.
