Long story short, I'm now back in the gym after years of non-attendance. However, I've developed a pain in my right knee; I feel it most when I'm kneeling or descending stairs. I'm shopping around for a physiotherapist (I may ask a friend to suggest a good one), but the internet says that this may be due to weak hips and glutes. Honestly, since I'm not a kinesiologist, I can't say for certain. Has anyone ever experienced this before? Do you know what might have caused it (for example, bad form, weaknesses in other muscle groups, or perhaps imbalances, which may explain why it isn't both knees)? Any ideas would be helpful! Thanks!
