Im sorry to hear that you have contracted parasites. Its a horrorfying, lonely disease. Most on here with parasites have lost their jobs and mates and just about everything, forced to a survival mode that can be mote than scary and depressing. Im not sure that u have roundworm. It cld be some other species. Can u do a colon flush and enema and see what comes out. If u see worms put on some gloves and fish them out and post to help identify. Ive heard of others having those black hairlike worms but i am not familiar with them. Just wanted to reach out and let u know that u are not alone. If its pin worms u may want to try the reeses pinx, alot of people have had sucess with that med, tho u will probably need to repeat the med several times.
