In the past month I have been getting massive headaches daily and episodically, my vision has started to get radically bad and when I look up my it sends excruciating pain to my head. I also cannot see out of the corners of my eyes. I have crazy mood swings every day. My memory is absolutely terrible, I always forget things way to easy. Every now and then my arms and legs shake non stop for a long time. I also get very light headed and nauseous all the time and some times when i stand up, my vision goes black.
