Yes you need to see a special doctor. I live in NJ and there is only one or two doctors here that do it. It is not covered by insurance so it can get pricey, but it seems worth it. I feel if i knew about it before i had surgery and i would be healed by now, but the surgery and scar tissue pain and stuff is a lil tough to get rid of.
The injections act like the opposite of cortizone. They regrow tendons and ligaments, etc. because it causes inflamation so that your body sends more blood to the injured area. Iceing and cortizone dont let blood get to the injured area to heal it.
