Female, 37 yrs, 5'4" and clincally obese

For about 2 months, I have been having a sudden, medium to sharp pain under my right rib cage. This usually presents itself after sitting or bending. Upon straightening, I get a terrible pain that feels as though something is caught and needs to be released. When it finally does “release” the pain is completely gone, but until it does I cannot expand my lungs fully as the further I do, the pain gets worse- as well, I cannot straighten fully until the source “releases” itself. Just today, I felt a small twinge of something similar on the left side. I’ve also felt feelings like something is being stretched near the sternum when I am stretching/bending to take things out of the dryer. The pain under the right rib cage will occur horizontally on a slight up-angle directly under the rib cage and it will also shoot vertically, directly on my side.

Unsure if possibly related, but during this time (and over the last year) I’ve had constant dizziness of varying degree and “type” that cannot be fully explained by doctors.

I am clinically obese, so wondering if this may be the cause.
