After working for a couple months in the Caribbean walking and carrying a 70-200 F4, 1Ds, 580Ex my elbow finally gave up the ghost.
Lateral epicondylitis is treatable by rest and anti-imflammatories and cortisone injections. I've resorted to massive ibuprofen injections and when not shooting carrying the rig in my left hand instead of walking around with it in the hand strap on my right arm.
I can't use a monopod too well on the sand but it appears I'll have to modify my shooting and carrying habits permanently in order to avoid pain/discomfort.
And to think when I said I bought the 70-200 F4 for it's portability people chuckled and thought I should have went 2.8... I cannot possibly imagine walking 5 miles a day with that sucker on my arm.
So don't let it happen to you if you shoot professionally or a HELL of a lot. I'm doing about 250-300 shots a day hand held/walkaround.
