I am currently 4 weeks in on TPF with no surgery. I am in a brace that can be removed for a shower and sleeping. When I am sitting, my leg is propped up. Twice today while sitting I have had this pain that just came out of the blue and was like I was electrically shocked in my knee. It was kinda on the top towards inner side of my knee. It hits real quick, kinda takes my breathe away, and is gone within 30-60 seconds. The first time it happened, it was right after I put ice in but the second time was just sitting here. Anybody ever had this? I would love to think it is norm and nerves healing but I manage to be scared about everything.
