I'm 52 and probably late stage peri (periods 100 days apart, etc) and for the past couple months have had a feeling under my right rib of something stuck under there! Just an odd, dull discomfort, not pain as such. I had something similar a couple years back but ultrasound discounted gallstones. I don't feel like it's food/digestion related. I don't have nausea or GERD or anything like that. Just this strange sensation/fullness at the very bottom of my rib (more towards flank side as opposed to nearer sternum). I wondered if it might be colon-related or a muscle issue? I have a desk job and also have shoulder stiffness/arm pain at the right side, mouse/desk posture related? Obvs my anxious brain is in overdrive!
I hope someone might have had similar or be able to shed some light on this!
