I have Blasticisits and also D Flagilis ... and have very unconfortable tummy, bloating, pain, nausea and headaches. I am also Immune suppressed as I m on methotrexate 10mg once per week for RA, however this seems under control. I have been very sick for 8 months now stemming from diareahha, nausea, headaches, chronic fatigue, body weakness. Could the parasite be causing these systems... ? I didnt get on well with Flagyl and so wondering what other treatment I can take... both conventional and natural ?? Thanks
