haven't been around much recently, mainly due to pressure of work, I've just started running again but only slowly on the treadmill.
Anyway, for a while now I've been getting a grinding sensation on the outside of my right knee which lasts for about 5 minutes, normally between 10 and 15 minutes into my run. After the five minutes it goes and I've had no problems. Went for a 30 min slow run on Tuesday lunchtime got the sensation and ran through it as normal. When I got home in the evening my knee was very stiff and felt tight down the inside and outside, and was slightly swollen so I didn't run yesterday.
Ran exactly the same today but the sensation lasted for about 10 minutes and started on the outside of the knee and then moved to the centre of my knee, my knee is again very stiff down both sides abd also swollen. Additionally I am getting what feels like a twisting sensation inside the knee when I'm standing up.
Does anybody have any ideas what the problem could be? Should I go to the doctor's first or visit a physio? Amputation maybe!!!
Any advice and comments gratefully received.
