My husband, 82 yrs old is having pain under the rib cage,can be sharp pain, but is a dull pain most of the time. started three days ago, sharp is hitting harder, dull pain is about the same. He did have a bowel obstruction, about 60 to 70 days ago. Spent two nights in the hospitable, after they pumped his stomach. He had been better since then. Any suggestions would be appreciated.
