Blood blister formed on my labia minora 7 weeks ago. It popped & healed, but I have soreness & pain in pelvis & back. CT scan came back normal. Is it an infection? I don't have any STDs.

Pelvic pain: inf ? Symptoms as described should be carefully investigated by a physician. Ask your healthcare provider to check for herpes I and II, as episodes as described may originate from a viral cause.
