Anyone have experience with PRP injections to address Achilles tendon pain?

I'm looking at non surgical options to address an Achilles tendon issue. MRI shows thickening of the tendon, some scarring, as well as a minimal tear near tendon insertion to heel bone. I also have bursitis in the heel. The Orthopedist suggested that after we reduce the current inflammation, we follow a non surgical approach, since I am trying to continue long course triathlon training and racing. I am currently doing some research and will get a second Orthopedist's opinion.

So my question is: Has anyone had Platelet Rich Plasma therapy (injections) to address Achilles issues? And if so, have you resumed running successfully after treatments?
