I have rotator cuff tendonitis. Looking into PRP injections but cant afford to go to a clinic. Is it possible to do it yourself at home? All you appear to need is a centrfuge and some needles, etc. Shouldnt cost more than 600$ for a potential lifeling PRP supply. I am concerned about injecting into the RC, as in the videos on youtube the doctos appear to be using ultrasound as a guide.

Thoughts?
