I have had this problem and have been told a number of things. Number one; Your not getting enough exercise. If you don't use a muscle, it will eventually shrink until it is taught (probably misspelled) and cause sudden pain
Number Two; You may have something stuck. One doctor once told me my so-and-so nerve went UNDER the so-and-so vein, causing pain. Another tells me It is a pinched nerve. Another tells me to go to a accupunturist.
I dont know if this helps, but My suggestion is to go ask YOUR doctor. Mine are never all that good, but listen to what he says carefully and then bring up the details and do some research online. Hope I've helped! =D
