Hello,..as u wrote ur mother having stones in gall bladder..n she is critical..as we are not having th USG report n haematology reports..without these very difficult to comment..but one thing I can advise u to immediately opt for surgery at a competent centre asap..as there is no other treatment other than this..once u can subside th pain n other symptoms but they can aggravate at any time in future also...so go with ur doctor advise if u feel him well competent okk
