Rachel! Way to use the forum!
And you are right we did not go over the AC joint. Super easy though. I wold use 1/2″ needles right at the AC ligament/ joint space and let them marinate for 10 min. If it is more degenerative, I would do a little periosteal pecking on the bone on either end.
I had a baseball player with a degenerative AC joint and we were able to expand on the time between injections by weeks when we would needle. (It was his last season as a player and surgery was not an option for him. He was not a starting player and it only flared up on him if he played/ swung the bat hard several days in a row).
So worked great for us. I know Erik, our other teacher who works hockey and sees acute sprains all the time also uses it and seems to help his guys feel better.
Keep us posted!
