how goes the battle desi?
my guess is you slipped into that funny in between realm of pain, where you have spent so much time in pain once you experience a break in the cycle you feel like you are out of the woods and want to make up for lost time. so you do everything you wish you could have done but coudnt because it hurt to much and it overwhelms your body. since you have such good experiences with the sgb my guess is that you probably will bounce back following another one. usually the cycle for a sgb series is with the first one you experience x amount of relief with the second you experience x days plus y and with the third you experience x plus y plus z.
the excessive activity is a normal reaction and the fact that your body's response is limited to one side seems to indicate that this is a normal flare cycle. with the sgbs you will continue to experience relief (unless you have hundreds of them...at some point they just stop working..go figure).
if i were a betting person (and as a crps patient i would say i am

) i would say try to take it easy over the remainder of the holiday (easier said than done especially when you are the cook) and after another block you will return to that wonderful place of feeling pretty good most of the time. the block wont last forever, and the more exertion you apply to your body the shorter that space of time will be.
every crps patient who experiences a large amount of relief following a block or a series of blocks will probably do exactly what you did (i know i did), and i know when you are curled up in bed miserable the thoughts rolling through your head are what was i thinking, no worries next time you will know you can do some of the stuff around the house but you cant get it all done in a week.
i am sure you will bounce back after your next block and you will return to feeling good. its ok to stumble...we all do.
you will be ok
enjoy the holidays...your doc will get you in and fix you up
