Pulling a muscle.

[Supafly345]

Holy cow, I hope that I am not the only one who knows what a pulled muscle is. Rog, if you pulled your muscle you woulden't be able to use it without releasing a soul-shattering scream. I doubt you pulled you muscle.
A pulled muscle is when the muscle itself rips in two. Meaning cast. You would notice abnormal muscle placement as well. The muscle pieces would be bunched up at the muscles connecting points.

If you ever got a pulled muscle you would be out for weeks. It is very easy to repair, but in the meantime you will be basking in one of the most painful muscle-related pains you will ever feel.
