@therealjb It's interesting to me, because i was long ago given PRP by an ophthalmologist for my eyes, and it only worsened my MGD sensitivity. (I wound up helping myself by instilling pure-water followed by preservative-free Refresh.)

Furthermore, one of my podiatrists told me he got PRP for his bad hip, with zero results.

IMO PRP, though it may help some people some of the time, is camouflage for the real thing, which is MSC (mesenchymal stem cells). Its MSC's which helps most people most of the time, versus some people some of the time.
