can hymen be intact after 4 yrs married? Painful intercourse

Hi,
Welcome to ehealthforum,
Hymen once ruptured does not get back to pre-virgin state. Pain during or after intercourse that you describe could also suggest possibility of vaginal infection, vaginal dryness, injury, cervicitis, cervix erosion, pelvic adhesions, endometriosis, PID, etc. The exact cause can only be made out after careful evaluation. Consider visiting your doctor/gynecologist at the earliest for further thorough examination and further evaluation to look for the underlying cause for the symptoms that you describe. Treatment as indicated (based on examination findings and investigations results) would be started to help you control the symptoms. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. If infective cause is detected, get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment.
Take care.
