extensibility
First put some ice on it. Then you should take a bath in warm water and epsom salt. Then take some pain reliever, then stretch the muscle.
Rest and stretch. Try Tiger Balm or Ben Gay if you need to mask the pain for a sporting event.
what is a pulled muscle
I always stretch before and after I run. It allows your body to loosen up and not get you injured. If you don't stretch, you also risk getting an injury or pulled muscle.
It shouldn't hurt, if it hurts the muscle is not warm yet. When it will be warm, you will see the same stretch will be painless.
Yes, wait for it to heal.
the muscle spindle detects excessive stretch within the muscle , it response and makes the muscle contract
As much as it may hurt have someone rub the muscle as hard as you can handle. That is not the only thing you have to do. Also stretch the muscle. I am not the smartest so I am sure there are other things you can do but that's what I do.
You can have hip injuries when you pull a muscle by rotating your hips. Also back injury if you do not properly stretch or force your back to move in a way where it is not flexible. The most common injury is probably a pulled muscle witch you can relieve by aplying heat to loosen the muscle. then stretch it out carefully a little bit at a time.
