Why does my wife have headache after intercourse?

Q: My 23 years old wife always have headache after intercourse. The pain does not start immediately but after 8-10 hours of the intercourse. How can this problem be treated?

A:This is a common problem, usually caused by swelling in the uterus, called PID (Pelvic inflammatory disease). She should go for check up. She will be given treatment for fifteen days and that should clear the problem.
