I had an hour off for lunch a couple weeks ago and couldn’t really workout because of a solid TFCC sprain leaving me unable to lift almost anything (never-mind even being able to do manual work). I realized that not many people think of this little guy, so I give you – I am: Mike’s TFCC

seems like you have been doing too much manual work without RECEIVING manual work on your forearms. Go get some good NM massage Mike!
I couldn’t agree more!
