MSM WARNING: I began having heart palpitations and chest tightness & discomfort after taking MSM for 3 weeks. It did help with hip pain but I had to discontinue it because of side effects. This forum is excellent! I'm glad to know it wasn't just my imagination & that other people have had these side effects.

WARNING!
I started taking 2 grams of MSM per day for about 9 days (NOW Foods brand in capsule form). As soon as I swallowed a capsule, I became excessively thirsty. I'd even wake up in the middle of the night to drink 2 full glasses of water. I perspired much more (perhaps from all the water I drank), which didn't bother me because I liked sweating more in the sauna. I got pains in my body, especially in my arms and hands - I felt like I was getting arthritis/tendonitis, which was weird because I thought MSM was supposed to help if you have that. My bowel movements increased from 1 per day to 4. At night I'd notice my heart was beating fast. I can usually walk for miles but I got really scared when I found I had trouble walking fast and breathing well on a fairly short walk. I was searching the web for allergic reactions to MSM but couldn't find any. The only other supplement I was taking at that time was 50mg of Ubiquinol (CoQ10). So I stopped taking both. The thirst and breathing/heart problems went away fairly fast, but the pains in my arms lasted a few weeks. Since the time I stopped taking it (probably 1.5 months now), I've been getting sharp pains in my upper abdomen (left and right sides), which have been slowly getting better.

re: Side Effects of MSM --
I am so grateful to God for this forum. I can totally relate to DL from CA, that posting is almost a total duplicate of what I just recently experienced. I had been having constant pain in my legs and feet for over a year and had, had my fill. I did some research and came across the MSM. I was also diagnosed with osteopenia about the same time, so I decided to try it.
Two night ago I had my son take me to the ER, I was having a lot of what's been described here concerning the heart beating weird, anxiety(I guess) because I don't know how else to explain how I was feeling, shallow breathing, heaviness of chest etc. All this had been going on for some time and I normally could meditate on scriptures and it would go away, this night was different. My jaunt to the ER, showed irregular heartbeat, palpitations to be exact. However, all of my blood work came back normal, showing no previous heart attacks or heart disease. I have been referred for a stress test. I am going to discontinue my use of MSM and see what happens. I will keep you posted as to what happens after I am no longer taking this product. Oh yeah, one of the other effects is headaches. I also started getting headaches that wouldn't go away. I sorta fluffed that off figuring it was a sinus thing, however, these aren't sinus area specific. So, I'm thinking this is all related. Time will tell.
I am very happy for those folks that this works for. Of course, everybody's metabolism is different, so what works for others may not work for someone else. Anyone else that may have related info. that would be helpful to my situation please feel free to e-mail me. God Bless

★☆☆☆☆WARNING!
re: MSM suppliment, 1000 mg -- I had some bad symptoms similar to Joanna's taking only 1 capsule a day for several days. I'm not allergic to any substances to my knowledge but awoke with difficulty breathing, very sharp pains in my sides, an ache in my back,and my eyes dried out. I'm not real fond of this MSM supplement. Also, my mood was downcast.Watch yourself with this one..
