Reality hit me today. I'm starting to age. I've had pain in my knee for about a month now. Nothing serious, no loss of range of movement, no swelling, no bruising, etc. Just minor discomfort. I finally gave in and went to my doctor today. He's not a sports medicine specialist, but he's a former athlete who's very receptive to sports injuries / concerns. He pretty much molested my knee - feeling around while he moved my leg, pushing, pulling, etc. He told me that the ligaments felt fine, and that it's likely inflammation. He suggested that I stop running (I jog a few miles three times a week) and, to the point of this topic, start taking an NSAID before I play tennis / work out / etc. I'm a pretty big guy, 190-200lbs depending on diet / activity (had a six-pack in high school at 185, FWIW) and he suggested "three or four Advil" before sports activity. I'm not much for medication, over the counter or otherwise. I'm a bit leary of taking that much of anything habitually. Should I be? I don't think he's in the wrong, and I've gotten good feedback on his advice from guys who've been through multiple knee surgeries. Just nervous about making over the counter pain releivers part of my daily workout / tennis routine. EDIT: Wanted to add that I've been through the podiatrist bit, and I'm confident that I'm wearing the right footwear and not aggravating things in that manner. No one traumatic event is associated with this, so I really think he's on the right track with the "wear and tear" bit.
