I've had this for years, way before I started running. Sometimes when going up stairs ( and extremely rarely when going down stairs), I feel a slight twinge in my right knee. The thing is, it never happens while running. Can anyone shed any light on this? Do I just have to strengthen my quads - I'm doing that now anyway, along with various other leg exercises on my Total Trainer.
One other thing, if I get stitch while out there running, I usually try to run through it - which usually works; is that the right thing to do?
Thanks in advance for any advice.
