So I took Monistat 3 for what I thought was a yeast infection. I tried to make an appt with my doctor but can’t get in for 2 weeks. After the monistat my vagina dried up really bad and now has a weird sour smell to it and I’m having a sharp constant pain in my uterus that feels like it’s being squeezed and it hasn’t gone away for days. What could it be or could i have made it worse by self treating?
