I have been using my MBP for the past 6 months. And I happen to use it for pretty long hours at a stretch. Both my wrists gets burnt (no scars on the skin) with a burning sensation under the skin above and below the wrist extending to my lower palm(area near the wrist) even long after my usage. The way I have been using the keyboard on the MBP was to rest my arms on the left and right aluminum space available on the MBP - no external keyboards or mouses. Could anyone out there suggest me alternatives as I cannot hold both my forearms up to use the keyboard for long hours - not to mention the radiation I still experience. Thanks a lot for any advice and I hope this would help lot of other people out there experiencing such burning sensations.
