Due to xeomin injections for headaches a couple weeks ago, I am having severe symptoms of brain fog, including executive function problems (planning, concentrating, etc), short term memory prob's, depersonalization, distance from emotions, and vertigo. Please, can anyone share how long this will last? I'm having a rough time functioning and my work entails the ability to do all of these things. I am not able to connect with friends or family either. This is very isolating, and scary.
