Thank you for the query.
Your symptoms can be caused by gallstones, urinary tract stones, urinary tract infection
, abscess in the abdomen, ovarian or uterine infection
. For most of mentioned disease morphine or codeine wont be helpful as it does not relaxes smooth muscles (it makes the spasm more intense) what is the main reason of pain in this conditions.
Morphine should be helpful with an abscess pain and you should have also fever with this condition.
As you have had surgery recently, I suggest you to visit your doctor and have checked mentioned conditions. Abdominal ultrasound
(CT wont tell if there are any stones or not), blood work, CRP, liver tests (AST,ALT,GGTP,AP), bilirubin
, amylase, urine amylase and urine analysis at first.
In a meanwhile hot bath, Metamizole
and Buscolisine should help with the pain.
Hope this will help.
