Could be heart? Did you feel sweaty from the pain? Women hurt different than men.
If the pain was so bad you had to take a strong narcotic it is best to have it checked out. They can do a ultra sound and it doesn't cost oo awful much. I understand you have no medical, I hope you can fix that soon. My brother had to go in the hospital where he was living in LA and he had no insurance. Apparently they have a program out there that covers uninsured people. He went to a almost brand new hospital and after he received one bill (for over $100,000 dollars and yes it was very serious) and never got another bill.. He still lives in the same place. That was over 10 years ago. Thankfully he now has medicare.
Also hopefully all the changes in the medical insurance will enable you to get some somehow..possibly you qualify for medicaid? I don't know your situation. But so sorry you are having to go through that. It's bad enough to be sick but even worse if you have to figure out how to pay for it. Is there any clinics in your area?
And in referral to the comment about childbirth and gallstones..I had a girlfriend that had to have her gallbladder out after she gave birth. Then she had to come home and take care of a new baby..
Also a guy I worked withs wife had to have her gallbladder out a few days after she gave birth. Then on top of that she had to go back in as after the operation as a stone got lodged in her bile duct or somewhere.. They were able to dislodge and withdraw it through her esophegus with a tube and a scope..yuck!
Somehow childbirth must force the gallstones out or something..possibly the condition already existed and the birthing stirred them up.?
