Help...my skin has different color blotches.......?

i play tennis everyday so im out in the sun quite alot....the thing is, is that on my back, i have blotches of lighter skin. i am very careful about stayin in the sun too long......so i always wear a sweater when i play....ALWAYS...no matter how hot. im worried because i dont have any discoloration anywhere else on my body...just my back...at first i thought it was because i wasnt scrubing my back hard enough when i showered...but that didnt help....PLEASE help.......

Reply:It might be vitiligo...a condition where areas of ur skin start losing pigment and turn white. There are some treatments that can help, especially if its just in one area...I would recommend that you see a dermatologist.
Reply:Research vitiligo and look at the pictures of it, that's what it sounds like to me.
