Hi, Thanks for posting in HCM. I understand your concern. Presence of gall stones in the gall bladder and stones obstructing bile duct would cause pain in the abdomen. Due to this, there is elevation of enzyme alkaline phosphatase. What investigation has been done is alright. You need to get treated for removal of gall stones by consulting Endoscopic Surgeon. Hope the information provided would be helpful. All the best.
