What can I use for this? This got diagnosed by podiartrist and told me to go to pharmacy to get cream, but there is so many different types, she never told me what to get.

I have extremely bad fungal toenails and this has gone into my skin and is now so hard and cracks, and is at times really painful to walk on.

Any ideas what I can use for the skin? and what I should be taking for the toenails?
