### input:
I have had severe abdominal pain accompanied by a blocked feeling and nausea since a holiday to egypt in october.  I never had proper diarrohea or any vommitting but was diagnosed with gastroenteritis although another doctor said it wasnt.I have had all tests including scans, stool samples, colonoscopy, endoscopy, blood tests which have all shown no problems.I have seen my GP, private doctor and gastro specialist and have been told to give it time.No medicines seem to help including proton pump inhibitors, ulcer treatments, ant acid injections, digestive aids, acid reflux treatments etc etc.My diet is good, i eat small amounts often and I am generally fit and healthy other than this.  My diet doesnt seem to effect when the pain occurs/worsens.the pain fluctuates but it is always there.  It is sharp constant pains/bloating feeling beneath the stomach and around the sides which feels worse when bent over.I can only liken it to massive trapped wind but treatment for this such as windeze makes no difference or even increases the pain.The current specialist has said I had a viral infection which has affected my insides and they have not recovered and so are still cramping causing pain.  There has been an odd good day but generally no improvement and I need something to help me cope with the pain/blocked feeling.Please help.
