Hi Countrymom

You probably could get a photo on here through an external link but I really would not go to this bother when the best thing for you to do is to see your doctor or a dermatologist.  I am neither of these and even if I were...nobody can diagnose you over the Internet.  If you need treated...you will have to see a doctor pure and simple.

It could be anything but again...if it is growing or changing in size and color...this is a definite sign that you need to get this checked out by a doctor. 

The New Zealand Dermatological web site has many images you can look at to see if your skin changes match any of the photos...but again please see your doctor!

I am sorry I cannot be of more help to you.
