Your doctor may not be able to predict what might happen for you as an individual.
For many women the pain gets better with time. Most women have no serious or life threatening problem underlying the pain. Many women find that they can cope better with their pain after they have been given a thorough explanation of the nature of the pain, including previous test results and possible causes of the pain. They can also cope better when they feel reassured that there is no serious or life-threatening disease present.
If you are not comfortable with the final diagnosis, you can ask for a second opinion.
