I have been experiencing a dull pain in the upper right side just under the rib cage. My stomach is very bloated and fat. I am constipated. Sometimes I feel a hardening or lump at the top of my belly. My right side from head to toe gets the pins and needle effect. I recently had a severe case of positional vertigo (probably not related).
I think you need to get ultrasound examination of the abdomen that will confirm if there is any abnormal swelling in the abdomen or a lump. This will also show if there is enlarged liver or gall bladder than can also give rise to similar complains.
