Hi just want some advise really. I run three times a week completing 3 miles each time. I also play lawn bowls, I practice each Monday night with an extra practice on a Weds night if i am in a match at the weekend. Recently i have developed pain in my left knee, no swelling, just pain which ibuprofen helps with. I question is it the bowls, with all that crouching which is causing it or the running, or a combination of the two. I am so anxious that i am going to have to stop to rest my knee and worried that if i stop the running i will loose the fitness that i have so far achieved.
