I have herniated discs in my Lumbar spine. I have experienced pain for the better part of 5 years, sometimes so debilitating i can t get out of bed. 29 yo F, 3 kids, 9 years in the Army. Moved to Colorado Springs, CO Oct 2008, pain started Jan 2009. I thought it was because I had another child (pregnant Jan-Sep 09). Anyway, on Friday, I drove 14 hours straight to San Antonio Texas for the weekend. I had ZERO pain upon arrival, even after the drive (I was in pain during the drive) and had zero pain all weekend. Could the high altitude be causing (or at least exacerbating) my symptoms and pain?
