HJ trail. Started out gingerly due to pulling a muscle in my lower back this morning. Back got loosened up, but then had an unfamiliar sharp pain under my R kneecap.... grrrr...walked for about a half mile and then continued jogging which my knee didn't seem to mind.
Cause may be due to using different inserts that have higher arches ? Plus perhaps back pain induced a different use of leg muscles. Plus I weighed more today than usual
