Have you ever had a serious work-up for TOS (Thoracic Outlet Syndrome) or other C-4 to T-4 spine injuries/inflammations? I had serious IBS as a result of my injury. When I was properly treated for the spinal and related radiculopathies, my IBS cleared up. It returns from time to time but will clear up with the same physical therapy techniques.

When mine acts up, I get bloated and have other IBS symptoms.

pcslife, You don't indicate whether you are male or female. Females have a propensity to IBS due to the hormone cycles they go through monthly. These same hormone cycles can exacerbate PCS.

A work-up for TOS would include X-rays to determine if you have false ribs on your cervical vertebra. The false ribs can cause nerve inflammation and dysfunction to the gut. As one ages with these false ribs, they become more problematic due to the slow compression of the vertebral disks bringing them closer together.

After my first PT session, I had a huge BM as my large intestine started to function better. The PT also was able to release a spasming ileocecal valve (the valve between the small and large intestine) I needed to take a spasmotic and softening laxative for a year to get the intestinal muscles working stronger. They had become very weak after 18 months of minimal function. The main symptom of this was continual BM's like a deer. Small turds, no normal size BM's.

Sorry for the gross subject but the treatment did not take place until a proper diagnosis was made. The TOS or TOS like injury is common in whiplash injuries.
