I've a sore in my have that won't heal. help me please. it' will try to heal and it will open back up. it's very irritating ?

Here's The Skinny: If you have a 'sore' that isn't healing, anywhere on the body but especially sun-exposed area,then you should see a dermatologist to help figure-out what's going on. A month would be enough time for most things to heal so if it's been longer than that,get it checked out. Many things can cause a delay in healing but a delay in healing can look like something that might be growing, like a skin tumor
