Weird Headaches

Day 5 (i think) of 25mg and awaiting my drs call back. I’m dealing with these headaches that aren’t headaches? My head just feels so tense. best way to describe it, I go to the chiro weekly. Tylenol seemed to help a little but gosh, i hate these. I’d rather have a regular headache. Is this a side effect? I almost want to take myself off of it.
