I am requesting the names of doctors who specialize in systemic roundworm infections. I have been infected for several years throughout my body with roundworms; even though I have taken anti-parasitic medication with some success, I am unable to clear my body completely. I recently passed a very large roundworm, and I can feel them crawling in my body. My greatest concern is that I can feel one crawling between my skull and my brain. This causes pain, burning and pressure inside my skull. I am so sick and scared, this is very disturbing to me. I am afraid of damage done to my brain and body. For the past ten years I have had CFS / FM and have learned that parasitic infections are not that uncommon with these conditions. I am hoping that someone will be able to refer me to a doctor or clinic who specializes in treating systemic roundworm. Maybe you have ideas of where I might look or who I could contact for help. The doctors I have seen are inexperienced with this and at this point do not know how to help me. My attempts to locate a specialist have been unsuccessful. I would be most grateful if you could help me in any way.
