Hi, I have had a darkened neck for as long as I can remember now. I used to not pay attention to it much, I'd ignore it but now that I am 21 years old (213 lbs) I've been feeling real bad over this. Ever since I can remember, my neck has been very noticeably darker than the rest of my body. It's the same with my armpits. I've used dove deodorant for a long time, and I thought that's what had been causing the darkening of my armpits, since I have barely noticed an allergic reaction to this deodorant. But that doesn't explain my neck. I try to avoid taking pictures unless my hair covers my neck because of the darkening. I recently went to the emergency room and a nurse tols me I should really get it checked out cause it could be diabetes. I do not feel sick or have ever felt sick before. I have a 5 year old, and even when I was pregnant, I never felt sick or anything. There were no complications at all, so I really don't know what could've been causing this. Ever since the 4th grade, I remember having this. It is not a hygiene issue, so I don't have any clue or explanation as to why this is happening and won't go away. Please help. Like I said, I have barely noticed allergic reactions to deodorants and some body lotions, could that have caused it since I had used these things over the years without thinking much about it? Any help will be greatly appreciated, thanks in advance.
