I have been having chronic vaginal and rectal itching that led to pelvic muscle spams and alot of pain...the muslces have calmed down but I CANNOT get this rectal itching to go away...and then it leads to vaginal itching and chronic inflammation. Could this be because of parasites? I esp notice the burning/itching when I try to wear pants too. ALso, i don't seem to notice more itching at night (as supposedly that is when the pinworms are most active)
