hi, I play tennis professionaly and lately I have been having a lot of pain at the back of my heel. a doctor told me that I have an inflamation in the achilies tendon where it meets the bone. I was taking some anti-inflamatory pills and getting some ultra sound treatment. I would like to know if there is something else that should be done. its been 2 months now with no improvement. I stopped playing and I would like to know how long this usually takes? is it a really serious injury?
