Now pain in this region can be due to a number of conditions. Since the pain ONLY occurs on breathing, then it is very likely that this is related to the muscles of the abdomen more than anything else. This would cause pain on deep inspiration and would sometimes also cause pain if you do a twisting movement. This would be easily diagnosed on a clinical examination. The treatment is usually with increased intake of water and also with the intake of electrolyte rich fluids. If that does not work then you would need anti inflammatory medications like ibuprofen or aleve. In some cases muscle relaxants may be needed like flexeril or even tinazidine.
Now apart from the muscles, it is possible that this is arising from the region of the gallbladder. If you gallbladder was removed, it is possible that the common bile duct or the portion of teh CBD which is left behind is inflammed which is causing pain when the diaphragm touches it on deep inspiration. This would also cause pain in the region on palpation and may also cause other symptoms such as radiation of the pain to the back and in long standing cases, yellow discoloration of the skin and sclera and change in color of stool and urine. This can be diagnosed on a clinical examination and also with an ultrasound. The treatment depends on the nature of the inflammation for example an infection is treated with antibiotics and obstruction is treated with stents etc.
But given the pattern of the pain, i think this is more muscular in nature than anything. I would suggest adequate hydration and use of electrolyte rich fluids along with OTC anti inflammatory agents like motrin or aleve should be able to control the pain. if that doesnt help then muscle relaxants may be needed like flexeril.
