I started to get this jittery and shakiness, nervousness feeling (like on steroids - but I m not) all over. My heart flutters and my hands are visibly shaky - tremors to the point it s difficult to type and especially write and pretty much everything else that you can think of, it s very difficult. I am extremely cold and hot at the same time but have to cover up and sweating, but still cold. I am also beat red everywhere - all extremities - head to toe. Had a left sided migraine all day 7/3 and it subsided when I took a maxalt around 9 or 10pm. All the symptoms started about 2 am. I took unisom and benadryl to try to go to sleep , which I have taken before many times, but I think it did the opposite and made me more awake. I ve been up all night (currently 6:11am 7/4). The concerning symptoms is the redness it s never happened before. Pls adv.
