Electrolyte : Alterations in your electrolytes through loss in sweat may be the cause. Try drinking fruit juice with a small amount of added salt. Drink enough water so your urine is mostly colorless. If the symptoms persist for more than 2 weeks, it would be prudent to seea doctor. Wish you good health!
