Hello. I am having trouble with my Achilles Tendon in my foot. I somehow injured it running 5 KM runs. (Something which I was not previously well conditioned for. Mind you I was in decent shape, but not used to long distance running. I am in my mid 30's.) I have tried not running for a period of over 14 months and doing calf raises during that time to heal the injury. It seemed to improve a fair bit, but when I went on a recent run it once again swelled up giving me pain. What can I do to permanently heal this injury so that I can run again without swelling or pain?

Is Human Growth Hormone an option? If injected into the ankle area would it help with the healing process? Can a Doctor prescribe it? Thank you for your response in advance.
