Before I realized I had parasites I had real problems. I decided to take MSM at maximum dose and did this for 6 months. Most of the symptoms disappeared. I still had weakness and spasms so I requested an MRI of my brain. The MRI showed lots of lesions. The biggest being 12mm in the back left. But there were no visible calcified cysts on the MRI to indicate parasites.
I think the MSM helped kill a lot of parasites. I think the brain lessions were either tape worm, now dead, or inflammation caused by histamine. Since this is the alt med forum I can't tell you what I did. Start with cleaning up your diet, taking supplements, and determining what you are consuming that is irritating your body/brain.
I wish you luck. You are at the same point I was many years ago.
