<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi.. I am 25 years female. I had intercourse on 18 and 19th of September. Ever since then I had tingling sensation in my lower abdomen n legs.Yesterday I suddenly felt my body got hot and I was sweating for a while. Severe headache is one of the main issue in lower pelvic abdomen pain.Can you please tell me what is going on with me? And how can I resolve it?  <response>: Hi. Thanks for your query. The history of intercourse followed by tingling sensation and pain in lower abdomen, headache, body feeling hot, lots of sweating is all suggestive of -Severe PID-Pelvic Inflammatory Disease-Severe UTI- Urinary tract Infection. I would advise you the following:Blood, urine and stool tests. Ultrasonography of the whole abdomen and pelvis. Get started on a course of an antibiotic, metronidazole, paracetamol and painkillers. Your sex partner will also need the same course.
