I would like to know more of your experience on this issue. I have noticed many of these symptoms and much more since June of last year. I've seen doctors but only at the ER I do not have a primary and just got insurance but no one has confirmed a parasite(but treated me for them)and look at me like I'm crazy. I still have the symptoms and have what I'm starting to believe is PTSD about the whole situation. Recently in my lower abdomen has been hurting so I went to the ER again where they gave me a CAT scan and have seen my lower intestine is swollen and scheduled for a colonoscopy at the end of the month. If you can give me any information on what you've experienced or your findings that would be greatly appreciated I am extremely nervous about the whole situation.
