Because some of us, like myself, have doctors that don't feel it's necessary to treat pain and think we should just live with it. My old doctor told me to take ibuprofen, and I did and it destroyed my stomach. My new doctor tells me to live with it. I'm tired of looking for a doctor that cares so I have taken matters into my own hands. I thought about asking for a referral to a pain doctor, but I really don't think my doctor will give me one. The closest one is over 70 miles away anyway.
