Chronic headaches I've had for weeks/months now?

It started with what I thought was Tension Headaches (felt like wearing a helmet a couple sizes to small) and this went on for a while and seemed to be helped by taking Tension Headache Excedrin, but once the medicine wore off it was back, but the one spot that had the more painful headaches was an area at the top/back right side of my head, and sometimes (not all the time) if I bent over it'd flare up, but worse if I sneezed, or especially if I strained going to the bathroom and put pressure on my head like that. All of these headaches are mild in nature, in a sense that I've never had a headache where I can't function, but sometimes like when listening to music you get annoyed enough to stop because you don't feel like it anymore because of the pain. Then I had earaches for a few days, I still pressure there every so often but now the pressure seems to be all up front mainly in my forehead, or right above my ears, around my eyes/nose. I do not have a runny nose or soar throat though, so I don't know if it's sinitis. I still have pressure/pain all around the top and back of head too just not as bad as before.
