Muscle strain at one time has effected all of us, from the weekend athlete who over did a workout to a mother lifting up a heavy toddler.
Here is some simple solutions to help you through this muscle strain.
Rest, most muscle pain will go away by itself soon enough, so just rest it and don't try to use the muscle until it's healed.
Ice can bring down the muscle inflammation, but if the pain is very bad use heat.
If the muscle pain should be in your legs, just make sure when you lie down to keep your feet higher than your heart, and the swelling will go down.
If you get cramps in your legs at night you might want to take a calcium supplement, since deficiency in that mineral can cause cramping. Also think about the amount of potassium you have, potassium can also cause muscle cramping.
Warm up before any exercise, if your muscles are sufficiently warmed up you greatly reduce the chance of injury. Also warm down after a workout, I find this to be effective in reducing stiffness the next day.
Eat Pineapple, pineapple contains the enzyme called bromelain which helps repair injured tissue.
