MSM supplement.. good or bad for swaying?

So long story short, I am having joint problems. Arthritis is very common in my family as so is bone degeneration. I have an appointment Tuesday to see what the deal is. I thought I could handle it but my knee gave out on me and I almost fell down a flight of stairs, thank God for hand rails. Anyway depending on what they say I will see what my doctor says about me taking MSM. Since the issue has spread from my knee to my hip I have to try something, there is no way I can carry a baby for 9 months without trying something. (I know because with ds I had issues and had to wear a contraption to help with the issues that I was having.) Anyway if no one knows that's fine, I was just wondering. TIA

If you need it, you need it.

doesn't appear to sway strongly either direction to me.
