Life seems to be like a yo-yo

Well at the moment I really seem to be up & down with flare-ups. Things had just settled down & then last week was full of appointments & I was out nearly every day. By Friday night was back to feeling like I was getting the flu again - joints ache, skin sore, feeling cold & shivery. I really gets frustrating to not be able to do even a little bit extra without feeling like this.
