I dislocated my patella back in August 2013, and 3 weeks ago had surgery to correct it - I m having tingling and numbness in my hands and feet consistently since the surgery. It s not getting better, and in fact seems to be getting worse. The amount of time between numbness is getting less and less, and it s gone from tingling to almost 100% numb at times. I m due back at work in the next few weeks and have to be able to use my hands to type. Should I be concerned? Or is this something that may fix itself?
