Should I be worried about the pains I'm having? It is an internal pain and runs from hip to hip, mid way between my belly button and vagina. It is a squeezing feeling that is at times immobilizing. It happens on a daily basis and often interups my sleep. What could be causing this? Could you please recommend a course of action?
Many Thanks.

Go to the doctors it could be many different things. Anywhere from an std, ovarian cyst, pregnancy & other possibilities I'd see your doctor as soon as possible.

Cycts definitely might be the problem
Or too much sexual activity
Go get an Ultrasound asap ( make sure to fill your bladder before you go there )
