over the past 2 months my son has experienced getting a quick on set of chills and muscle pains - it seems to only last about a day - but it has occurred about 5 times. I asked him if he had a fever but he hadn t taken his temperature so he wasn t sure. He works out often I was wondering if it is maybe some mineral deficiency etc. he eats well and drinks a lot of water but I thought the muscle pains might be the need for some potassium etc.
