trichomoniasis
"The first time they gave me Flagyl in 4 pills to take all at the same time. It worked great and I cleared up. The second I was given the same 4 pill dosage and the symptoms cleared up for about a week until I got my period, then the discharge, smell and itching came back with a vengeance.  So back to the doctor I went and this time they gave me Tindamax."
