Hi! My name is Danny, and I'm 24. My first brush with RSI was at age 16. I've been a heavy guitar player at the time, it was my passion and I spent hours practicing, until one day I felt pain in my left wrist and fingers, pain combined with stiffness and some tingling that would eventually go away if I took a break from any activity, yet came back swiftly as soon as I went back to using my hand. A few doctors later I've had a general tendinitis diagnosis and hot/cold therapy combined with NSAIDS. The treatment gave me only temporary relief. I pretty much gave up guitar at this point. Fast forward five years, I'm 21 and working in software dev. My left hand worsening slowly but surely over the time period, when my right hand suddenly joined in. Symptoms pointed to carpal tunnel syndrome, doctors agreed, however I passed EMG tests. The doctors and I were clueless. I found myself effectively handicapped as far as computers went. I've had to give up video games at home to keep my job. I'm forced to pace myself to conserve "stamina" and look for other ways to press the mouse - switch hands, use elbows, other kinds of workarounds. The index finger on my right had fell completely out of use for the mouse, I couldn't bear to use it. In other words, hell. 2013 brought me vocal dysfunction and discomfort with using smartphones. I've started looking into nutrition. Hell, maybe I'm eating wrong? I've branched out into sports, thought that maybe, just maybe, getting fit will help. I was swiftly rewarded with Achilles tendinitis and arm stiffness. Driving became a hated and feared activity, pressing the pedals and steering started to cause noticeable discomfort. I couldn't undestand why this had happened to me. I'm young, yet feel old and broken. A week and a half ago I stumbled upon Sarno and read Healing Back Pain. It sounded too good to be true. I felt so stupid for all the years wasted. I've felt immediate relief for a few days. Needless to say, I was overjoyed. Hit the gym, hit the guitar, drove freely. Yesterday, the symptoms came back with a vengeance, I panicked. That's why I'm here posting and starting the program. I hope this can help me. Here's a question to you folks: if Sarno is right, TMS is responsible for RSI symptoms, does that mean RSI doesn't exist? Tendinitis, tendinosis? If. I go run two hours everyday, won't I hurt my Achilles?
