Pain in under below lower left ribs above the abdomen since 2 mnnts which comes n goes most of the time.go for a ct, mri or sonography?any blood test?

Probably : Constipation. The only organ tucked under those ribs that you would feel in the front is the spleen which would be felt on physical exam. The colon is there too and if you are constipated caused pain there. To be constipated you can go everyday but poops are usually not like bananas but round, hard, and cause straining. If you have it try miralax(store brand ok) ;eat4fruits, 5 veggies8 waters a d.
