uh oh. Sounds like an inflamed tendon to me. Does it feel almost hot? Not a medical term but the best way I can describe how mine felt. Ice and Volterol cream helped mine heal plus resting it and a Vulcan elbow strap. Fingers crossed no re-occurrence despite playing with the PD (maybe the gut is helping in this regard) Babolats do have a reputation for being hard on the arm. I think my bout of TE was brought on by using full poly and swapping between too many different racquets.
