Injury happened outside the gym about 6 weeks back, took the neighbour’s dog for a walk, a huge beast, it saw something and attempted to bolt while I held its leash. I could feel it pulled something but I’ve checked:
my rear delt is painful to massage but has it’s strength;
front delt fine;
medial delt feels fine but I’m getting a pain when I laterally raise much more than a filled coffee cup. I waited for this to clear up by itself but the pain’s still there.
I’ve performed Neer’s test and the other RC test, Neer’s produces pain but no (apparent) loss of strength. Both internal and external RC strength same as before (which I know as I rehabbed it in full early last year)
