Sudden aggressive activity of GA

All of a sudden after almost 18 years of it being not a big deal, my GA is going crazy. In the past 2 days it seems to have gotten much worse, current areas getting worse and new areas starting up. Also, all the areas where I have spots are swollen and red and pretty itchy. This follows after a weird episode on Tuesday of my hand turning blue and freezing cold, which was diagnosed as Raynauds Syndrom. That also happened again today. I don’t know if there is any connection or not. I have also developed some strange rashes. 3 different areas, all look totally different. I feel like my body is planning a mutiny. I feel like something is wrong, I just can’t pinpoint what it is.
