I'm entering week three of using the Dunlop Black Max, and for the first time in my life I'm experiencing elbow pain. Dunlop Black Max 85 square inch, 370g, 8 pt. headlight, 50 flex, 45# Gosen Sheep Micro 17g I doubt that it's the racquets fault since the strings break before going dead. The frames themselves are also specced well, and in like new condition despite their age. The sweet spot is liquidy smooth on these Black Maxes, though whenever I swing out I can make a crunching noise, even with the ball dead center in the stringbed. I can't tell if it's sound from the strings or the frame itself. Hmmm... I'm posting here because I'm trying to diagnose what parts of my technique may be contributing to this problem. I have a very whippy open-stanced full western forehand that doesn't flatten out, a one handed back hand slice, and two handed backhand everything. I've had my one handed back hand looked at, and though I lead with my elbow I never use it for flat drives or topspin. The pain is most acute when I'd play a forehand after I've been hitting for a while, and eventually the pain reaches my shoulder. I suspect that the pain lies in the fact that I've been shanking alot lately since I'm returning from a sprained ankle, though I'm at the point where I'm not longer compensating for a weak ankle. What should I do besides pay attention to footwork, flatten my forehands, and use two handed backhands when possible? EDITS: paulfreda - I've been playing 8-10 hours per week for a couple months. How to describe the pain... akin to running into a wall, hard, elbow and shoulder first. Deep throbbing pain at the shoulder and elbow joints, as if my arm had been held together under pressure but now allowed to decompress and pull itself apart. Lasted a good 30 minutes after play. papa - Yes, I've been arming the ball in more than I should. Sprained left ankle + I'm a lefty + forehand = things get sloppy. eagle - I'm working on a video. nellie - Previously I'd used the Dunlop Hotmelt 200g in my sig for a good six years, same weight and balance as the Black Max. From what I've gathered so far, I need to step through my forehands while using less arm, tuck my elbow in, and don't swing out with one-handed backhands. I do have natural gut on hand, they're going in hybrid with Gosen Sheep Micro next time I restring. I believe strongly that the root of my tennis elbow lies mostly in the quantity and variety of shanks I've been displaying. Every mishit yields a sickening crunching sound that's likely tearing up my tendons. Most importantly though, I'll be sitting out for a week so I can put myself back together.
