Hi, For the last 5 months now I've been experiencing left knee pain after cycling which comes on a day or so afterwards. It typically lasts a few days which then allows me to cycle again. Its just below the kneecap to the inside with some swelling. I assume its patella femoral pain. Walking can also aggravate the problem. I've had a pro bike fit so assume setup is correct. I think the problem resides around me having the inability to contract my left quads when stood up. Also, when I sit down on the floor with my legs out in front of me and I contract my right quad my patella moves towards me as normal, however when doing this on my left leg my quads DO activate the same as my right but my patella doesn't move as much as the right - it seems tightl!!!!!
