The original Microsoft Natural keyboard saved my career.
Two weeks out of school, I had unendurable pain in both hands. I bought a Natural keyboard, the pain went away immediately, and only comes back when I use a laptop keyboard for coding for more than an hour or two.
The fact that it comes back after an hour or two of laptop keyboard use strongly suggests that you've not addressed the underlying issues. That's one of the key things I see cropping up repeatedly here - "I've found something that helps with my pain, if I stop the problems come back."
I regularly use laptops, standard keyboards, and have no problems. When I had RSI, it was bad enough that I couldn't hold a fork for almost three months, and typing was an exercise in agony.
Seek help from a good physiotherapist, but you'll need to do some research to find a good one.
Also, see if you can find the bad habits you have that promote your injuries. I have upper body muscle tension and poor posture, and when I first recovered from my RSI I was having problems all the time with writing, typing, absolutely everything. It turned out that those problems weren't bad feelings, my hands and forearms had lost a significant portion of their strength, yet I was working just the same as I had been beforehand.
