Been meaning to post on this too... you just reminded me...
I tweaked my collateral on middle finger quite badly last week at the wall, very sore when I got home, painful enough to wake me from my sleep that night. Gave it a day then flossed it on the hour all day.
Astonished by the results.. pretty much pain free by the end of the day, much better range of motion (generally). Did the same the next day, then have only done it occasionally since.
One week later and apart from the at the extreme end of range of motion, there is no pain at all. Fairly happy to go to the wall tomorrow and take it easy at first, but I'm reasonably confident of a good session.
Hmmm - now to try and fix this shoulder!!
PS - Sam - what were you using to wrap the knee - a theraband? or something more dedicated ?
