Hi, I was using a tree pesticide and got some on my hands, and have been fatigued and waking up with a headache for the past 2 months, as well as feeling on the cusp of being sick (slight sore throat), but never get sick. I work all day just fine, get tired, go to bed, and wake up feeling exhausted. It was very bad for the first 2 weeks, and now it is lower grade headaches. I'm not sure if this is the cause of it, but checking to be sure?
