My son is vomitting dark green vomit, come and go stomach pain, no fever and a headache. Does he need to go to dr?

If your son is less then2 months. I would go to the doctor immediately, I would go to the doctor anyway if you don't know how to treat him or ease his discomfort. Why Wait ? Dark vomit could be caused by a number of things.

Tick

The green could be bile (gallbladder) and vomiting is a common sign of gallbladder problems, although not usually in children.

A phone call to the Doctor wouldn't hurt. Unfortunately we can't tell what is wrong. We also don't know the extent of his symptoms.

If I were you I would speak to a Doctor or a nurse practitioner.

Good Luck.
