To treat Pelvic Inflammatory Disease (PID), doctors prescribe a combination of broad-spectrum antibiotics to clear the infection. Standard treatment typically includes a single injection of ceftriaxone, followed by oral doxycycline, and sometimes metronidazole for 14 days. It is crucial to complete the entire course. For pelvic and leg pain, over-the-counter pain relievers like ibuprofen can help reduce inflammation. Rest and staying hydrated will assist with fatigue. However, because you are experiencing leg pain and body swelling, please consult your doctor promptly, as these symptoms require clinical evaluation to ensure there are no other underlying issues. You will feel much better once treatment begins!
