I was fine all day Monday. Then I got off the train at Meadowhall and felt this pain on the inside of my right knee. I thought it was down to the seats being too close together and I'd just been sat funny. However, I couldn't walk it off. It's worse when I'm lied in bed and on an evening than during the day. Although I do feel it when I straighten it and a slight twinge when I walk. It isn't excruciating pain.

Anybody else have/had owt similar?
