A couple weeks ago I started getting headaches on left side of my head. My neck is kind of stiff, my face sometimes feels fuzzy on the left side. Sometimes it hurts in my ear, sometimes my jaw , my cheek , and sometimes the left forehead . It is often accompanied by nausea. Almost never have headaches. No real changes in diet. Changed jobs a few months ago. Standing and repetitive motion for several hours at a time. Spending a lot of time on computer at home. What do you think?
