Thanks for replying,its my sexual function that has been damaged by one of the drugs i mentioned,the groin area below the belly button feels sensitive and an uncomfortable acidic burning bloated gas build up if my trouser belt is not loose and theres a huge reduction in sperm production,this diagram is the nearest to the area of the body thats affected, http://en.wikipedia.org/wiki/Inguinal_canal
Most antidepressants, and other drugs that affect brain neurotransmitters, can cause digestive problems. This is partly because they can affect serotonin which is mostly in the digestive system, and partly because they utilize pathways used by magnesium, and magnesium is very important in digestion. I think this is why there's also so much muscle cramping as a side effect of these types of drugs. Now, your question is a little difficult to pin down, because while you say it's gastric distress the location seems to be in a different area in part and you're claiming sexual side effects, which these drugs also produce. What exactly is bothering you, sexual function or digestive problems?
