It may be a manifestation of a nutritional deficiency. Take multivitamins, available over the counter. If that does not relieve your symptoms in 2-3 days, it would be prudent to consult a doctor. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
