I have always suspected my TE in 2016 wasn't typical TE. Serves and FHs hurt, but backhands never did. I had lateral elbow pain, hurt to grab plates off the shelf, hurt bad to press down on an aerosol can with index finger, etc. Not so much with the door knob turning, that seemed fine. Supination with green flexbar was bad pain. After looking at lateral elbow anatomy, maybe I figured out why mine was not typical. I am suspecting it was tricep injury at connection of elbow (different connection point than typical TE injury). I have marked in red in the first pic where my pain was: The tricep connects to the Olecrannon, typical TE is at the Lateral epicondyle. I had mild discomfort at the TE location (Lateral epicondyle) in the pic above, and seemed to respond to flexbar and forearm massage. Now, I am starting to wonder if it was ever Lateral epicondyle related, and the flexbar stuff really didn't do anything (I did find knots and sore spots, but I suspect all tennis players have them in the forearm if they poke around). I do remember responding well to adding tricep massage later in the rehab. Anyway, thought maybe someone here might know more about the arm/elbow anatomy, and match that to the symptoms I had. It always seemed odd that I never had any backhand pain. It does seem like anyone with TE might as well massage the tricep also, don't see how that could hurt. The following shows the tricep connection point: Edit: Just noticed when I do flexbar eccentric TE exercise, you also work the tricep. Maybe the flexbar TE eccentric exercise also works the tricep tendon connected at the elbow. ???
