BETTER BUT WITH SIDE EFFECTS
I keep re-injuring my knee from strenuous exercise. I find that MSM heals the tenderness in my meniscus very fast -- usually overnight. However, I started to take double the dosage last week and also started having side effects for the first time! You never hear about the side effects of MSM, but I think it probably happens to people more than they realize. I started to have shortness of breath and a racing heartbeat at night when I lay down to sleep. That lead to a slight panic attack because I kept feeling like I wasn't getting enough oxygen. I am not sure how MSM affects the muscles around the heart and or lungs, but it perhaps tightens them (possible?) causing this sensation. Would love to know if anyone experiences the same side effects.
