Hi, at your age and with this pain and constipation beginning less than a year ago, I am optimistic that you can overcome this before too long.
Have you ever had a colonic? Many people (including me :) ) find them helpful in situations like you are going through, and Oregon has an abundance of naturopaths and colon therapists where you may find some relief.
It's late here for me now, but tomorrow (Wednesday) I'll try to find you some references. Will you be in the western coastal area, or central or eastern Oregon?
Don't despair, there are a lot of natural options you can pursue to get yourself back to a state of optimal health and feeling great!
