Well, I took the physio’s advice about taking breaks and stretching more often. I can’t say whether it helped or not, but it probably didn’t hurt. I’m currently icing one elbow – I don’t have enough ice to do both.
In spite of her advice on how to modify it, one of the stretches still seems to hurt – not a nice pulling out the tension stretch type hurt, but a “damage the ligaments” type hurt. Bad hurt. I’ve got to figure out how to stretch “A” without hurting “B”.
