> A ganglion is likely not due to keyboard use or similar stress, but simply a small tear in the sheath. The small tear in the sheath is, effectively, the ganglion. (A ganglion cyst, for others reading this, is a tear in a tendon through which joint fluid exits, when it should not. The fluid is in a pouch, so it doesn't go anywhere, but the pouch being pushed through the tear by the fluid causes a bulge wherever this is on your body.) To say that's the cause is like saying the cause of a laceration is that the skin is broken. It's true, but it's not particularly enlightening. The question is what causes that tear to arise in the first place, and trauma and repeated strain are theories (though it seems medical science does not actually know the root cause of ganglions). So, it could be coincidence, but I was already having general wrist pain and numbness, and managing my keyboard use better solved both. > FWIW my mum (a GP) used to just whack them with a book. My research brought me across this home "remedy" very quickly. Modern medical science does not recommend this. (Mostly due to the risk of causing other injury to the area.)
