I have been using a roller - and still not convinced it does a damn thing whatsoever. My piss thankfully did not turn to blood like yours did - but no change in soreness at all.
it did ,you can't open a water bottle since using it
I have been using "The Stick".I have had a nagging little thing in my high calf area, low hamstring area on my left leg.I used the stick on that area rather aggressively the other day, as foam rollering wasn't cutting it. I must have had an adhesion of some sort, because the next day, I had a huge bruise, and no more pain.I like the stick far better than foam rollering.https://www.thestick.com/cgi-bin/commerce.cgi?preadd=action&key=DC-2475
I'll bet you like the stick . . . . . .. . . .
You could have used it to pry the cap off of that water bottle, stud.
