### input:
I have been dealing with chronic upper abdomen pain and nausea for about the last 6 months. The pain is in the middle and each side right below my rib cage. It seemed to have started after having my gallbladder removed. The pain started as just random episodes but has progressed to something I am having to deal with on a daily basis. It is almost a colic pain that will intensify and when the pain is at it s worse it is comparable to labor pains. I have been to 3 different doctors and have had almost every gastro test done: endoscope, colonoscopy, ct scan and a gastro emptying which they all came back clear as did all my blood work. I still have to do a test to check for over growth in my small intestines. This has turned my life upside down. Somedays I can not even get out of bed because the pain is so bad. I feel depression has started to set in because of this. I have had to deal with doctors that seem to not believe I am actually in as much pain as I am which makes dealing with this that much more difficult. If anyone has any idea of what this could be or suggestions for me please share. This is truly taking a toll on me.

### output:

Hi. Gone through the history carefully and repeatedly. I was just wondering about any other associated symptoms other than you have noted. One good thing is most of the tests are normal, at least it rules out the problem related to colon and stomach. Pain is in the middle and each side right below my rib cage ::: This suggests me that the pain may be due to overstretched nerves bellow the ribs. (You have not mentioned means there is no distension, vomiting constipation). I would advise you to try tablet gabapentin 300 mg start from once a day to twice and then thrice if helping for a week or so. This will be diagnostic and prognostic also. Please discuss this with your Doctor. MRI of the thoracic spine may also help.
