Have you/anyone found out what this could be?
Parasites can be dealt with, because of what we decide to eat. Parasites reject things that are hot. I became paranoid myself that i had worms in my system, i used to swallow half a sausage whole and not cool it down before swallowing. I believe that if the worms tried to eat the sausage it would be painful for them and they would die. Its drastic, but i believe it helped put me at ease. In any case speak to your doctor.
