I've recently been suffering from painful kneecaps - pain behind the patella when walking up stairs, jumping (I play volleyball) and sometimes when cycing.
I went to see the doc and he suggested some leg exercises to strengthen the vastus medialis, which will help keep the kneecap stable. The exercise is done seated: raise the leg straight in front, rotate the foot outwards to 45 deg, the raise the leg, noting that the VM is working. THere asre other exercises like squats and lunges of course, but this is the one that has raised a niggle.
All seems well and good (aside from the fact that I have tight hamstrings / calves so need to stretch them in order to properly do my leg raise exercises), except that when I lower my left leg I can *feel a click. More, Mrs NBT can *hear* it. This doesn't bode well, I fear, Dad's had both hips replaced already. Do I need to get it check by the docs?
