I have a constant headache, fatigue, lightheadedness, dizziness, feel like I m going to pass out at times --especially if I get too hot, no energy whatsoever, worse dry eyes than usual, shortness of breath --i.e. just walking from a grocery store to my car in the parking lot, sometimes it feels like my heartbeat is going to jump out of my chest, and I ve noticed some chest pain here and there...???
