I know I have a parasite in my blood. It started out with round, black, large flea size mark on the bottom, front of my neck between the the 2 bumps of my collarbone. When it didn't scratch off, I tried tweezers, I could not tear it out and the sound it made was of metal scraping against metal. After a few tries it burrowed into my skin leaving a hole that quickly was covered by I guess skin. It took maybe 1/2 of a second to be sealed. If I squeezed it as hard as I could it shot blood quite a distance. It has metaphorsized a few years later and I have this first brown, now yellow jelly coming out of my anus and a lot of gas for a couple of weeks. It felt like there was a bowel movement coming but it never came. It has curtailed and I now see my dog has the problem. Doctors I have seen never find anything wrong and imply I am making this all up. I am not one to complain or ever really dwell on ailments. I need to know what dangers, if any, lay ahead. My husband has a parasite too. Though happening all at the exact same time, was a little different. I know it is the same . We refuse to go to a doctor now, it is degrading. Is there an alternative, something over the counter maybe? I just lost my job and do not have money to spare, if you can't answer without payment, Ill go without your answer. Thank you anyway.
