If you sit at the computer constantly, you should also consider setting up your work environment more ergonomically; set up the chair and monitor correctly, and invest in a good keyboard and in a good mouse. For the keyboard/mouse, decide what's best for you, try several if you most, read reviews about them, and then make a good decision that will help you enhance your life and your productivity.
You have to bear in mind that the good old keyboard and mouse are the devices you use the most among any other device, even more than the tv remote. Most people use a keyboard/mouse for about 8 hours a day and 5 days a week. This is a lot of time, predominantly if you're using a shameful keyboard/mouse.
I know that countless people use the included keyboard/mouse that comes with new computers, and at their job, they just use the keyboard/mouse laying in front of the monitor, and never think much about it. However, you have to realize this is not necessarily best for you, and in most cases, these will be mediocre that may cause you carpal tunnel syndrome and health problems in the near future.
As well, most people will use whatever keyboard/mouse as they say "it does the job", without realizing than a better keyboard/mouse, ergonomic or not, will help reduce the risk of injuries and help them become more efficient and productive.
Honestly, you should consider investing more money in yourself and in your health. Don't buy the cheapest products, don't buy just any that "will do", don't use the mediocre keyboard/mouse that comes "free" with most new computers.
Coincidentally, I just finish participating in a survey for a new corporation that is in the process of creating ergonomic computer products that I find very interesting, and they're asking people to participate in this survey as feedback is always helpful.
They're rewarding participants who wish it, by entering them into a draw to win exclusive computer products.
I hope this helps in your recovery and prevention of cts.
