my endoscopy showed slight irritation in my duodenal bulb (6 months ago). I also had a colonoscopy performed at the same time. I am having sporadic (weekly) discomfort between my breasts ( a dull ache) located under my left breast about 6 inches above my navel that can feel very uncomfortable. Sometimes, I believe that it may be causing me to have upper and lower back discomfort as wekk and I wonder if it could be causing the occasional side (Charlie horses) that I experience in my side ribcage area? I am 54 years of age and I had a gallbladder ultrasound that showed no gallstones.
