Bike Elbow

So I went to see an orthopedic surgeon yesterday about my elbow. Thought I might have cartilage trouble, as my elbow gets super sore, particularly when I've been doing a lot of riding. Takes him 30 seconds to diagnose 'Golf Elbow', caused by an inflamed tendon in the elbow. Basically a Repetitive Strain Injury (RSI), which needs no surgery, just topical treatment with anti-inflammatories and maybe some physio.

So I got to thinking about it, and messing about to find out what action was causing the RSI, and realized that it was covering the front brake with two fingers when I ride, which I have done as a habit for 20 years or so. When I was riding the Greek Alps recently and constantly on and off the brakes into the endless bends (Yeeeeeeesssssssssss!!!!!!!!!!!) the elbow got really sore, so it all makes sense. Living on Iboprufen for the last two weeks after having flipped an Enduro bike (Nooooooooooooo!!!!!) it went away. The anti-inflammatories cleared it up.

So. The question. Covering your brake and clutch with two fingers is fairly bog-standard practice. Is this 'biker's elbow' (as I have now dubbed it) a common thing to all riders who do this?
