My  husband is in his 19th year of prostate cancer. His PSA is below 2. He suffers from severe chest pain, vomits a lot, suffers a great deal of gastroestinal distress and stomach pain. Doctors say the chest pain and stomach issues aren't related to his cancer. They can't diagnose him. He sleeps most of the time, possibly induced by nausea and pain meds. He's 74. He has been severly ill for about two months. We've tried to go to Mayo but they don't accept out insurances. He is scheduled for a gall bladder test tomorrow. We've asked for a referral to a Gastrointestinal specialis. Any suggestions?
