Yes, Crohn’s can cause pain under right ribs. It can affect liver too and cause inflammation of the liver. This can cause raised liver enzymes. If the enzymes are normal, then pancreatitis, duodenal ulcer, and uncontrolled inflammation in Crohn’s should be ruled out.
Take a late night snack. Raise head end of bed. Take Omeprazole empty stomach in morning and an antacid gel at bedtime. Refrain from smoking, alcohol, fuzzy drinks and spicy food.
Also, please consult your gastroenterologist to further manage Crohn’s. Take care!
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
You may also want to get on the Crohn's Foundation Forum too. They have so many patients who are well informed because of their own journey living with the disease.
