I have been doing PT 4 times a day to increase flexion. (currently 60 cold and 90 when pushed)
Over the last 4 days, after I assist the knee flexing, when I straighten the knee again, something catches under the kneecap. It's not mega pain, just the sort to make you gasp, a little like when you hit your funny bone. It's like a twang feeling.
Here's the thing. It feels like I'm aggravating the knee by making it twang like this, but I've been told to do the PT religiously. I have not seen my Os or my PT since this started happening, but I can already feel the knee stiffening up because I haven't done so much PT.
Any ideas what could be happening?
Should I carry on doing flexion exercises?
Please help
