Sharp stabbing pain in middle left back side? Dr. Roberto Feliz Dr. Feliz. Middle left: There are many causes of one sided back pain: localized muscle strain with spasm, facet joint irritation/inflammation is your most likely cause. The facet joints is the site where the vertebral body meet in your back.
It began with: - general feeling of nausea for one week and diarrhea. - extreme bloating- I almost look pregnant (but I am definately not!) - 1 week later stabbing pains on my left side under the bottom rib of quite a high intensity for short periods of time. -->I went on nexum for a week and it made no difference, if not worse.
