I've completed Week 4 Runs 1 and 2. After Run 1 my right knee bothered me a bit, it was below the knee, to the inside. I presumed it was a tendon. It wasn't painful, just a niggle. Then after Run 2 that knee bothered me again. This was higher up, I think just under the knee cap, which sounds suspicionsly of possible cartilage problems. I iced it and took an ibuprofen. That was yesterday morning.
Since yesterday afternoon, my other knee just under the knee cap is bothering me. I'd like to do Run 3 tomorrow and carry on with the program. I feel I've been doing really well and want to not slip. But I don't want to damage my knees.
Any advice? I took ibuprofen this morning, and will probably take one in a little while.
