Back problems
mattchew: Look into the ideas and books of John Sarno.  He believes that many chronic pain "syndromes" that resist treatment are actually psychological in origin.I discovered Sarno when I came down with untreatable "RSI".  Eventually I got better using his approach.  My story is similar to Rachels (google for others):http://podolsky.everybody.org/rsi/Sarno originally worked with people who had chronic untreatable back pain.All that said, if you're not getting any exercise I would try that first.  But if you have tried that and a bunch of other things and nothing works, look at Sarno.
