How to ease sore muscles 
Apply ice immediately after exercise or injury. 
Ice prevents painful inflammation, and applying ice shortly after a work-out can slow down the inflammation process that causes muscle soreness. Wrap a bag of ice in a towel or t-shirt and apply to the affect muscles for 20 minutes.

Available options:
 - This method works best for sore muscles with limited activity or a moderate intensity of exercise. Try using a calamine lotion to ease pain.
 - Rest for 40 minutes and then reapply the ice for another 20. Never apply ice directly to the skin or for more than 20 minutes, as this can cause frost-bite.
 - Wrap a towel around your injured muscle and then apply the ice for 20 minutes. If you're struggling to stay in a position that's uncomfortable, there are other options, such as using dental floss.
 - Remove the ice and heat away immediately if you begin to feel relief. You can also apply ice therapy to specific back muscles.
The answer is:
Rest for 40 minutes and then reapply the ice for another 20. Never apply ice directly to the skin or for more than 20 minutes, as this can cause frost-bite.
