Is there anything i can get from the grocery store or drug store for my cervicitis until i can see a doctor?

First, see a doctor: It may not be cervicitis, but a host of other conditions. See a gyn doctor first before trying "grocery or drug store" remedies.

Cervicitis: It is usually caused by a bacteria, that requires antibiotics for treatment. In usa you cannot buy those antibiotics over the counter.Plus if there is cervicitis, chances of harboring another std is quite high and an std screen is recommended. Seeing an ob/gyn is more that recomended.
