I agree with JoyERD. Keeping a record of what you feel will be helpful when you see a doctor next time the pain attacks.
Keep a log of the times the pain occurs, the date, the intensity, and how long each pain lasts. Bring this with you to your healthcare provider so that he/she can have a complete record to go off of. This will give him/her a better means to help you. By having the complete information, you are more likely to receive the proper diagnosis. Best of luck to you!
