What else can be symptoms too? Like fever or what?
That same exact thing was happening to me just a few months ago. they were really really sharp pains in the head near the forehead that made you stop for a second they were so strong right? well if they were i went to the doctor and my doctor told me that it was really stress related and it could also have to do with sinus a little bit but more of stress. and she told me to just practice sitting down and paying attention to the expression i was making on my face and to make sure it was relaxed. and as for the ear thing thats probably more related to the sinus than anything else. yeah i would say the ear pain is sharp sinus pressure. :] hope that helped.
Yes it can, and eye pain.
