Sharp pain on my right side below my rib cage?

Gallbladder disease? If related to fat ingestion or cucumbers consider gb disease.The liver also lives there, as does part of the large intestine. Start with gb .
See below. May be something simple like a muscle stitch (spasm) that can be relieved by stretching muscles in that area. Or might be internal problem like liver, gallbladder, duodenum, ascending colon, pancreatic head, etc. If stretching doesn't relieve it, see pcp for evaluation, testing if needed, treatment options.
