i'm 14 and my body itches and burn when i get under the sun within five minutes even if it is not that bright. when i was a younger nothing like this happened until i turn 10. i rarely participate in sports events because of this and tried to avoid exposing to the sunlight. i did went to the doctor and they give me sunscreen to put on everyday when i go to school and i did. i wanted to know if this will go away in the future when i'm older and deficiency of vitamins that this happen.
