YES. I get crankly at no apparent reason. Sometimes, i will be sitting at the dinner table- and people eating and chewing drives me CRAZY. I cant handle it and just get really irritated, and I have to walk out of the room and just tell myself to calm down. It is completely normal and it happens completely out of the ordinary. The worst is when I am around a group of people an they dont know about my rsd and it happens... I have to just laugh about it... It is tough, but breathing exercises help alot
