I had a hysterectomy, but they left one ovary, I have had this strange pain in my insides which is hard to pinpoint since I have no insides.
The pain began after I had sex with my husband and that was 3 months ago. The pain began as a backache then I started getting a foul smell.
I recently used some antibiotics my daughter gave me, they were only six. Amoxcillin
And also bought some suppositories and that was for 3 days which I used, the pain is worst and I am worried.
Help!

I'm not a medic but you MUST go to your Dr/health worker and get this checked!
It could be anything but sounds like an infection of some kind.

Be brave.
