Q: Why are my stools green in colour? I am suffering from sinus and neck pain, behind the head and above the shoulder.

A:The colour of stool at times varies with the diet we take. Green stools are quite common and in itself do not indicate any disease process. It is more important to note whether you have any abdominal symptoms or not. You have not mentioned your age. I would suggest that you get yourself checked up for your neck pain in order to exclude cervical spondylitis. Also for sinus pain, you can have an ENT check up.
