Query: HURT NO MORE! THIS WORKS FOR ARTHRITIS PAIN

My 80-year-old mother has had osteoarthritis for as long as I can remember. In the past five years, she has experienced nothing but pain--24/7. Her doctor tried her on anti-inflammatory drugs but they upset her stomach so badly that she was even admitted to the hospital with a possible ulcer. She was taking Tylenol--but it didn't touch the pain she had. I bought Mom this book three weeks ago, and that very day she called her doctor for an Rx of Celebrex. It was amazing to us that within 7 days, she was able to move around more--without hurting. Now, 21-days later, she is out with her friends, going to the mall, and even babysitting my children again. This book DEFINITELY HAS THE CURE FOR ARTHRITIS PAIN!!! I cannot believe it's possible--but it is. If you hurt from arthritis pain--you do not have to hurt anymore! READ THE BOOK--take Celebrex!!! It will change your life the way it changed Mom's.
