So somewhat dip related... I took a two week hiatus from working out and then got back into the gym... did back/biceps one day, chest/triceps the next, legs and shoulders the third... took a day break.. than back/biceps one day, chest/triceps the next.... then randomly at night I went to pick up a box and as I did, I heard a rubbing/grinding sound in my left elbow.. i put the box down and tried to lift it again.. same thing. It seems that when I get to about a 90* bend in my arm, the sound appeared... i tried today to replicate it but the noise is gone.. though it's somewhat sore.
Anyone have any idea what this could be? I'm supposed to be back in the gym today but don't want to hurt myself.
