OK -- you probably have not hurt yourself, but if I could rewind then I would definitely not have trained ANYTHING for two weeks after the injury. Just like you, I thought that I would leave it a few days, then I did a really light high-rep workout on delts to pump blood into the area. This did not help. Then I avoided shoulders and just trained at about 60-70% on chest and back-- not good at all. Thing is, if your injured, just leave it - like me you are probably dying to get right back into the gym but why risk screwing up your training for years to come because you don't want to wait a few weeks?
Read Flex, do cardio, watch the boards -- be patient.
