Is it somewhat common to have a tension headache that lasts for
several days? I have had what I feel is a tension headache now for
around four days. I do not think it is bad enough to call a migraine.
Basically I have felt a lot of tightness in my lower-back scalp down
to my mid neck. Also sometimes a little tightness on the sides of the
scalp. I also would not clasify this as, "Pain," but more
as, "Tightness." What type of headache is this?

Thanks,

Josh
