How to ease chronic pelvic pain
Start by identifying the cause.
If possible, your doctor will want to identify the cause of your chronic pelvic pain, as the preferable form of treatment is to identify and resolve the underlying cause directly. If no definitive cause can be identified, your doctor will focus on managing your symptoms to get your pain under control.
Take over-the-counter painkillers. Over-the-counter (otc) painkillers can reduce levels of pain by interrupting the production of a certain chemical called prostaglandin which controls pain sensations.
