I fell snowboarding about 5 weeks ago onto my shoulder, couldn't move it much so I went to the doctors and he said that I strained my AC joint. He said to take 2-3 weeks off and could get right back into lifting. Is he wrong about it being strained, all the research I have done says that I must have a sprain, not a strain. Also, I have a lump ontop of my shoulder which he said would probably stay there, so I am guessing that it is a "grade 2 seperation." Most information I have read says that I cant make it worse so if I can tolerate it to go and lift. Should I tough it out or give it a few more weeks? Will it always hurt?
