A couple of months ago I strained my knee running up and down stairs at full speed repeatedly while cold (i.e., without warming up). At first I thought it was a simple strain, but it's now about 2 months later and my inner knee still bothers me sometimes. It's not painful all the time, nor when I walk, but sometimes I'll just feel some discomfort.
I can run up steps at a good speed while skipping steps (and I'm very overweight) now without pain, but still worry that I have some sort of cartilege damage. I've read that meniscus damage will give you pain/discomfort on the side of your knee. So my question is this: if I had any sort of meniscus damage, would I necessarily experience pain while running up steps (keeping in mind that I can skip steps, go up them fairly rapidly, and am overweight)? Or is it possible that I have meniscus damage yet can still do this without pain?
Any help would be appreciated. Thank you.
