Computing Pain

I am 31 and have been using the PC since I was 12. Not under optimal conditions. While it has been good for my career, it has been bad for my health. I've had problems with my eyes. Now, I'm focusing on my pain.

I have:

• lower back pain, giving me nonstop low-intensity headaches, making me irritable
• wrist pain. the bone too. mostly on the right. I am right handed.
• elbow pain. I made a mistake for months, working at home and leaning my elbow on part of the table.

I'm going to have myself checked next week. One advice I see is - get exercise. Yes, I lack exercise and I'm overweight.
