Now-edema in nodes(inner thigh)w/low grade fever. w/endometrial lining@2.1cm +fluid in cul de sac&ovarian cyst@recent er visit.should i return2er? w/no insurance what r thoughts on what's wrong

No ER: Perhaps there is a plan parnthood clinic in your town or other free health care clinic. The er is not the place for a detailed conversation about causes of enlarged lymph nodes in your inner thigh. It sounds like from your note that an ultrasound was performed. I also assume that blood work was done. I'd follow up via phone call in a few days to check on the lab results and seek a clinic appt.
