Hi John

How are you going now?

to answer your question regarding your gall stone - usually first sign of trouble is pain in lower right side of abdomen or back - usually in the middle of the night which is alleviated by staying upright. Some people turn yellow too. The gall bladder is more connected to the liver system than the kidneys so I cant see how it would cause pink urine...although remember that I am not a doctor and just stating my opinion.

6cm is awfully big - like golf ball size! Maybe it was 6mm which is still a respectable size and can cause all sorts of pain and grief. Although not usually life threatening, it certainly feels like you must be dying when the pain hits in the middle of the night! I will never forget the night I was called in to assist a friend many years ago, who was literally writhing on the floor with the pain!!
