Cysts or something?

Erin

For a few years now I get this horrible pain on my right side (like hurts to sit, walk, or stand)that lasts a few days, it usually comes about 2 weeks after my period. I’ve gone to the doctor she can’t find anything wrong. And I cant afford the pelvic sonogram.

Is there anyone else like me that can tell me what it may be and some home remedies?

Over the counter meds don’t help. Neither does heat.

Please help.
