These comments are from Rafa's doctor, Dr Angel Ruiz, regarding the radio frequency treatment,with it the sensory nerves which are responsible of the pain are partially inactivated,
The anesthetic blocking should only be used occasionally.The radio frequency treatment gets the same effect but lasts longer.Thus, if it works, it'll allow Rafa to train and play without having to resort to the anesthetic blocking.
In 3-4 days will have a first idea about the evolution, but a more reliable info on whether the treatment has been really successful or not will be available in 2 weeks.
