First Please do realize that it's impossible for anyone to be diagnosed over the internet for most of the skin disease. All we can do is give some tips so you can catch up with a dermatologist soon. So those moles are changing and itchy then i would suggest you to seek a professional help immediately. In your case its not really something you want to wait and watch.

All of us have some moles in our body and most of it are not dangerous. But if the moles looks different from the past or any new mole that first appears after age of 20 or more are of special medical concern. If you notice any coloured moles, which grow rapidly,can bleed, are itchy or change colour, you should have a dermatologist evaluate it.

Here are few tips:

Hope this helps.

I think it is better to err on the side of caution, but do not get too anxious about it. Unless the mole changes its shape size and structure, or has emerged recently, try not to get too worried
