Wow, another problem similar to mine! I had undiagnosed (I mean WRONGLY diagnosed) left hip and side and lower back pain and I couldn't figure out what was wrong for 15 years. I saw GPs, orthopedists, ob/gyn, er docs, etc. This pain was incredibly debilitating.
The short version of it is that it was my colon. Impacted colon presses on nerve = excruciating pain! The solution was to take Dr. Schulze 's Intestinal Formula #1 and eventually #2, but it is the #1 that gave me such astonishing results. My pain is gone and has not come back and all those doctors were wrong. I cannot recommend this product highly enough.
