I am a 28 yr old diabetic. I am pregnant and I have only ever had my husband as a sex partner. I have recently developed a chafing on my inner thighs in the crease near my vagina and thigh. It is painful and the skin seems red irritated and raised. There is no odor and no broken skin, but the area itches badly and is painful. I have made an appointment to see the doctor for my first prenatal visit, but until then is there anything I can do for relief? Or is this a possible STD? I believe my husband is faithful but I am worried as this has never happened to me before.
