Naturally, I am the worst offender of the A2 injury. about 3 years ago? since i did mine, slight tweak that pulses and throbs on the joint of the A2, tried cold bathing, heat and cold, deep heat, resting it for months, massaging it, stretching - over these 3 months, yet as soon as i get off the motherfucker of a megacrimp I can still feel it. Advice i would give is to take a couple of weeks off and imply the cold/hot contrast baths. mix with stretching/ get the blood circulation to it as soon as you can. I have a similar injury from surfing, shoulder fucked from a massive wipeout and putting my arm on my board, only to be wiped out again from another wave dislodging my arm over my head (in the wrong direction) and leading to a sore shoulder. This was a couple of months ago and it still hurts, when I do full movements like taking a throw in at football - this really hurts.
my shoulder still aches when I lie on it at night for example; or when i throw a ball in at football, has anyone had any experience in this sort of injury.
