Msm major healing crisis or something else?

I'm dealing with candida and parasite issues for few years now. Tried many different specifics, natural as well as pharmaceutical. With some good results, but, as most of you, I still have symptoms proving there is still much to do.

5 days ago I recived a package of msm. Started with a dose of one gram once a day, mixed with sodium ascorbate (on thursday). On friday morning I woke up a little shaky, but thought it was stress-related. Two hours later I started to feel really bad. Thirsty, coated tongue, nausesus. It took me one hour to get home and I thought I wouldn't manage to climb up stairs. I spent 48 hours in bed thinking I was dying. Horrible intestinal pain (moving from one side to another) and cramps, nausea (but no vomit nor diarrhea), high grade fever, complete loss of apetite. I was so weak I couldn't make myself to go to toillet. I felt like there was a second world war happening in my large intestine. The second day I had almost completly white bm and 3 more with white pieces / seeds. Nothing large.

It is a third day now, I feel a little better but still spending most if the time lying. I ate a tine pice of chicken with no sensation and then an egg, followed by loud and painful gurgling. My tongue is heavily coated, abdomen is bloated and I still have no apetite. The fever is gone but I am weak and tired.

Could msm made me feel like this? I am really scared it is candida re-attack or some kind of innflamation. Friend that visited me and saw how I was doing tell me to go to ER. If it mught be a parasite die off I see no sense in that.

Any similiar experiences?
