This heacache has lasted all day. it was gradual. i woke up with it but the pain got worse over the course of the day. i took one aleve, but it didn't help much.

There are too many: potential diagnoses that cause headache. Some are very serious and actually lethal and others not so much. Without obtaining a thorough history and examination and some testing these cannot be differentiated. You need to see a health care provider to determine what is wrong and how to help you. Go now!

Headache: A steady headache, nonthrobbing, generalized, associated with neck and shoulder pain is very characteristic of a tension muscle contraction headache. You could add Tylenol to the Aleve for pain relief. Massage, muscle relaxant and stress reduction all help. See your MD if no relief, headache worsens or development of vomiting or visual disturbance.
