I just joined a band a couple of weeks ago and so I'm spending a lot of time rehersing/practicing etc I notice that when I play powerchords for a while i get this pain in the top of  my wrist and i find it rather worrying. I only have this pain though for powerchords, for single note riffs and other stuff I don't have this pain. Normally when i play powerchords i put my index on the root note and i just bar the other two notes with my ring finger. Could this be why?? Any suggestions on how to get rid of this would be greatly appreciated. 
Thanks in advance
