Have pinching sensation at right side rib cage as well as front right lower rib cage. Also, discomfort varies in right groin area. Sleeping ok and depending on position when sitting or stretching out, things are more comfortable and less noticeable. The discomfort at times shows in different locations - but always on the right side. I ve noticed that at some of those times, I can adjust the tension on my belt or underwear and it makes a difference. This all seems to come and go because I shared these symptoms with my family doctor years ago and he attributed it all to stress. Just had a Medicare physical with a new doctor last week. Things weren t as aggravated back then, so I didn t mention it. The one constant is the pinching on the right side at my lower front rib cage. Thinking a combo of muscle pull (been working in the garden recently) and stress?? Thanks for your feedback.
