question: I fell on my butt while roller skating and used my hands/arms to break the fall. I m stiff (understandable) when I squat - but my right hand/arm took a lot of the force and my upper arm is really painful and hard to lift out from my side. I have moved my arm all around and know everything is where it should be - just wondering if I pulled a muscle or tendon or something? And wondering the best way to progress without having to go to the ER or something. I got back up and finished skating 4 miles - just want the best advice to try to heal on my own please.
