My appendix came out in April. Ever since, had a constant dull ache in the upper right quad of abdomin that radiates to my back, pain under my right arm, and some bloating & nausea. Best term to describe sleeping is 'shocky'. I can get really cold then really hot, (could be unrelated, but when it wakes me up & my side is throbbing-I wonder). Went to the ER 10/17 had CT (no stones), blood detected in urine; gall bladder ultra sound (looks fine); Diagnosis: Epigastric pain. Sent home w/ Rx for pain killer - Haven't filled it. DON'T want drugs - just answers. I am 46, have been told that I have IBS (since 19 yrs old-controlling diet, works for me) - never had this pain before; seriously just started after the appendix came out. I have no patience with exhasutive testing. What are the 'practical tests' that ought to be run; is there hope for a diagnosis/ treatment?
