After a C-section, your vagina may feel discomfort from labour and pain can stick around for the first two to six weeks after the operation. A Sitz Bath can be beneficial to relieving vaginal and pelvic pain, healing the vagina and helping you relax. You should only take a Sitz Bath after your incision has healed and your doctor says it's okay. In most cases, the incision takes about three weeks to heal.
