yes, i have had prp done in both elbows and have noticed a big improvement in both..
left elbow was a car accident and right elbow was a armbar hyper extension..
before prp, if i trained or over stressed my arms in any way (such as lifting heavy objects etc), i would be in so much pain after that i could barley lift a drink up to my mouth...
after prp, i can work out now (lift weights etc) and function normally after...
i still have pain daily but it is minor compared to before...
i would recommend and i would do again (probably will after 1 year)...
