I slammed my knee on a fall on hard concrete four weeks ago. I can walk without pain but if anything touches the knee, even my bed sheet, it is pain that I cannot describe. This has not gone away or gotten better in four weeks. Also, it feels numb at times, it itchy other times, and sometimes feels wet even though I have no open wounds. In the past week, the knee has started to hurt even when it is not being touched.
What you're feeling is called paresthesia which means altered sensation since your knee pains on touching it may be due to microtear of knee ligament or bursitis does your knee hurt we kneeling if It's, so then its bursitis for bursitis ice application is good home remedy other option include USG waves or cortisone injections
