injury rant!

Just want to let of some steam.. after my second week at my new BJJ gym, I finally got my GI! my sexy tatami estilo 5.0 blue sexyness.. what happened? i got an elbow from a fellow whitebelt right in my ribcage. I heard it "crunch" or something, and its been all sore and stiff since last night=( Iknow there is nothing to do but wait.. but how long should i wait untill i can do strenght workout without hampering the recovery of the injured rib? What ive read by google, it most likely is a injured cartilage. Going to the doctor is a waste of time... gaahhhhhhhhhh!! Is it stupid of me u think to show up to the class and sit in the corner observing what they are doing and taking notes?
