A quick history:
Age: early 30s
Training: Some dumbbell lifting in the past, not much barbell
- Lots of jogging for about 15 years
Issue: Pain in left knee, gets worse when I run. Possibly caused by jogging itself.
I've done some weightlifting over the last 5-10 years, but I've never really done a true weightlifting program. I just began doing Starting Strength and I'm now learning barbell lifts. The problem is that after years of jogging, I have some knee pain in my left knee (and it's really aggravated by jogging now, so I don't run at all). My knees also "crackle" a little when I walk up and down stairs.
I asked my primary care doctor to take a listen, and he said that it wasn't arthritis. Sadly, I can't remember exactly what he diagnosed it as, but he told me that the problem was likely caused by weak quad strength relative to hamstring strength and suggested that I "do leg extensions" a few times a week.
I've been doing the leg extensions, but want to start adding in squats, since they're integral to Rippetoe's program.
That said, I still have some knee pain and it became more pronounced after I tried a set of light squats last week.
QUESTION: Are squats safe? Is there anything I should be doing? Should I get an opinion of a sports medicine doc?
