According to my point of view to relief muscle pain the best solution and the easy way not only to keep muscle relief also to keep our body free and relax is do daily YOGA and EXERCISE daily and go to gym for maintaining body. Automatically this problem will be solved and also the body will keep relaxing from our pain.
There are plenty of Gym you can join and not only gym you have to take care of food also not to take junky foods as usual but there are some reasons where you can get some amount of more pain in muscle then you should immediately visit to the doctor i think he can give you best advise instead of time wasting here.
