Sharp pain

i get these sharp stabbing pain mostly at night on the bottom inside the left side of my right knee my first tkr i didny have this. im 15 days post tkr on my right knee

That sounds like one of my issues. I figured out that trying to do a deep tissue massage was helpful to redirect the nerve pathways. Doing this multiple times per days helps over time. Also, I found that icing underneath my knee was necessary. I wasn’t given a cold circulation machine from the surgery center…so I hadn’t realized how important it was to do. Let your doctor know so that it is paid attention to! Good Luck!
