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?
