I was recently in the hospital due to severe abdominal pian. An ultra sound was performed and I was told I have gallstones. I have all symptoms associated with this condition and frequently have had attacks at night especially if I eat late. Though now my stomach is somewhat swollen and my stools have become very abnormal. Ranging from diarrhea to verious colors mostly green and different consistencies. I am now concerned that a bigger problem may be the underlining issue though I am uncertin. What should I do? Any advice would be appreciated because I don't know if this something that needs immediate attention
