so, My son has been consistently complaining about recurring abdominal pain. Not, life threatening but definitely bothersome. He has had his appendix removed a couple of years ago can that be an issue as it is with person who have the gallbladder removed re: dietary restrictions. Also, it is more of nausea with burning pain he states. he has been recently to a Psych Provider for depressive issues. The practitioner stated that serotonin issues may be the cause of some of the stomach issues. He is beginning an ssri treatment for this is there anything i can due to relieve this issue.
