About 10 years ago I had serious "carpel tunnel" syndrome. I used to play Starcraft 2 competitively and was using a high DPI mouse that caused a repetitive strain injury. (P.S. Don't use HIGH DPI settings, micro movements are harder on the body than large sweeping motions). I stopped using computers for a month, when I started again, within 5 minutes of using a mouse I'd have tears running down my face. I couldn't specifically say what the problem was or where I felt the pain, it was just everywhere. Nerve pain is funny like that.
I went to a doctor, they started me on a muscle relaxer. I could maybe stand to use a computer for 10 minutes after that. Then they sent me to physical therapy. Physical therapy and frequent stretching did help. After 10 visits, I could use the computer for 3 hours a day, taking breaks every 20-30 minutes. The physical therapist told me most people would have recovered by now, and my insurance would only cover 20 visits a year, so I decided to look for a better solution. I went back to the doctor, and they sent me to get an EMG. They shocked my elbows and tested the response time in my fingers. Man did that hurt! Who would have thought directly shocking a nerve could be so painful?! They asked if it was both hands, and I said "If I tell you no, does that mean we don't have to do the other hand?"
The EMG showed that I did not have nerve damage, and at that point I refused to let them do carpel tunnel surgery on me. They couldn't tell me what the problem was, so I didn't trust their fix. I figured, I couldn't be the only gamer with this problem so I went back to researching. On Teamliquid.net, I found hope. Another gamer who had gone through this, and one who had actually found a solution:
Trigger Point Therapy by Clair Davis
This book talks about myofascial tissue, a thin layer of tissue that surrounds the muscles and helps them keep their shape. The myofascial tissue can bind up and form 'knots', that prevent the muscle from having full range of movement. This strain usually doesn't cause pain in the muscle that is bound up, but in the muscles connected that are overstretched and overworked to compensate. The book offered an explanation to the problems I was having, as well as an index showing me which muscles to work and where the bind ups (trigger points) would be. Working those trigger points wasn't fun, it was quite painful and it took me a while to read about it, find them on myself, and work them out. I was slow working, prone to stopping after the slightest improvement, and didn't work all the muscles when I first started. It took me a lot longer than it should have, but 3 months later I wasn't inhibited by pain anymore.
I really can't recommend this book enough. There's enough information it could easily be sold as a textbook for $120 and still be worth it. Over the years, I've bought 4 copies because I give them to people I know who are struggling with pain. Removing someone's pain is the best gift you can ever give. It's not an easy solution because it requires reading, finding the spots on yourself, and taking the time to work them. Pills are easier, but for anyone who truly wants help with pain, putting in the effort is worth it.
I did pick up a Thera-Cane, which the book recommended. It was instrumental in releasing trigger points held in my shoulders, without the Thera-Cane, I didn't have the leverage needed. It's a bit expensive for what it is, but for what it does, it's worth it's weight in gold.
I've been impressed with the book as it's a true cure for pain. There are a handful of situations that really do require surgery, and I'm impressed that the book correctly identifies when surgery is the best choice. It also has a few pages about fibromyalgia, and suggests that it is often caused by trigger points and can be resolved.
I also struggle with back pain. Around age 19 I was leaning over the engine of a car and my back popped in a bad way. It hurt so bad I had to lay on asphalt for 15 minutes before I could move. Ever since then I've had back pain (lower right, just above the hip), it comes and goes a bit, but it can get quite bad, enough so that I don't want to sit at a computer anymore. Spending time stretching and working trigger points brings my back into a usable state. I'd still like a doctor to tell me exactly what's wrong with my back, but they don't care that much. They offer pills and physical therapy, insurance in the U.S. has weird rules about what they will pay for, if they haven't paid for every possible alternative action, they won't pay for an x-ray.
If you end up getting the book, let me know how it goes.
