Could be okay: If you are otherwise healthy, growing normally, able to do your daily activities and schooling, you may ignore these as some of these issues usually resolve with age. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
