Hi there ~ I understand your concerns. Dizziness, pelvic pain and dehydration are all related. I wonder if you have a pelvic inflammatory disease and the infection is spreading to your system slowly. If you also have fever and are having lethargy, I would advise that you go to a gynecologist to have a pelvic examination. I hope this helps relieving your anxiety about this being serious. Also you can always walk into the ER if you do not have insurance and you will be covered although you might get a bill in the end, you will not be refused treatment. I hope this helps. Take care and have a lovely day!
