welcome to health care magic forum,
Your complaints are suggestive of some lymphadenopathy
) or intercostal muscle
strain.muscle strain will be pain full during movement or coughing/ sneezing
etc. in case of enlarged lymphnodes there will be pain and tenderness over that.
initially You need to have some NSAID (non steroidal anti inflammatory drugs) to relief your symptoms and never delay to consult your physician or gynecologist as early as possible to get clinically exemined.....
wish you a speedy recovery soon....
