Can you tell me what this is?

I have a mole on my left hip. It's a brown raised mole. I have had it since I was a child. I recently noticed it started hurting if I touch it or rub something against it. I also noticed the color is changing to a darker brown. It looks symmetrical to me and has an even border but I would like a professional opinion. I didn't think much of it until now because I am on vacation and have been exposed to the sun. I'm afraid it may be skin cancer.
