Since waking up with a really bad stiff neck a couple of days ago from overexerting myself, (you can
read post here) I've been learning about how to nurse my poor neck back to health.
So after researching online, a pulled muscle, strained muscle, stiff muscle, whatever you want to call it, is usually the result of tears in the muscle cells due to exercising improperly.
Which is why to protect your muscles you should always, always do a pre-exercise warm up as well as concentrate on achieving proper form in your routines, i.e., don't overextend your knees over your toes, don't bang your joints, etc. I understand now that the warm up is really important, especially going into a hardcore workout. The warm up helps pump more blood to your muscles which supply them with life-giving nutrients and oxygen so that they have the energy necessary to perform their job, which is essentially contracting, relaxing, contracting, relaxing.
The warm up also helps prepare the nerves-to-muscle pathways so that your brain and body are in a more ready state to perform physical activities. Incorporating some stretching is also essential to help "relax" and make your muscles all happy and pliable for a hard workout. I suppose you can think of it like caramelized sugar; when it's hot the caramel is fluid and pliable and you can do so many magical things with it, but when it's cold, it's hard and brittle and if you exert too much force, SNAP! and oops, you'll have broken something, just like your cold muscles.
Now should you end up with a pulled muscle from exercise, the standard remedy for mild pulls involve: cold compress (to alleviate swelling and pain), resting (well your muscles are in pain, so give it a rest), hot compress (to increase blood flow so all the wonderful goodies of nutrients and oxygen can be delivered) and stretching (well your muscles are sore and stiff, and probably feeling very down, you've got to help them rebuild their self-esteem with baby-stretching steps).
I essentially followed this formula to nurse my stiff neck, except for the cold compress because by the time I learned of the cold compress, it was already many hours after my injury. (You're supposed to apply a cold compress immediately after the injury). But, everyday I made sure I did a proper warm up before exercising, in which I added a neck stretch before and after the exercise. (I essentially followed the neck and back stretches shown in P90X). Afterwards, I would take a hot shower, making sure to bath my neck in the hot water while also stretching it out again. And, I avoided strenuous exercise in the injured area.
On the first and second day it was painful to just stretch out my neck muscles, but I noticed significant improvements with each passing day. And by the 3rd day I barely noticed the pain any more; and certainly by the 4th day the pain was completely gone. Given that in the past it has taken at least 1 week or even longer for me to recovery from a stiff neck, this experiment was quite a success.
