Question for a gynecologist. i live in vietnam and have a female personal issue. i am worried and in a lot of pain, please someone help.

Too vague: It's difficult to answer your question as it's very vague. A more detailed description of the pain (what part of the body, menstrual cycle, how often, how long does it last, other symptoms, pregnant, etc.) would likely yield a more helpful answer for you. Of course if the pain is severe, do not wait for an answer here and seek evaluation.

See doctor: Don't know what the issue is. I'm sure they have doctors in vietnam and suggest you go see one.

Need more info: In order to address your concerns, we would need more information about the nature of your problem. If you don't feel comfortable providing more details, please see a doctor near you as soon as possible.
