About 2 weeks ago, I felt really bad and thought it was just my sinus acting up, since I have sinus problems a lot especially during spring and harvest season. On a Saturday evening, I got to feeling really bad, I was freezing, my body ached so bad, the front and back of my head hurt, I felt horribly. So I went home took some Tylenol cold + Flu Severe and went laid down and went to sleep. I woke up at about 230 a.m cause I couldn't get comfortable and went an laid on the couch for a little while, then I went back to bed. I woke up the next morning thinking that maybe that I may have had the summer flu or something because I was soaking wet from sweat. I figure I was over it, but then about a week late it came back and it has hung on since. Every time that I get a slight chill my body goes to aching and I mean every joint in my body. Can anyone tell me what I dealing with.
