A year ago I went to the doctors with what I thought was eczema, he referred me to a dermatologist, They said it was an Ak, but it keeps coming back and now is very painful. This is the 3rd lot of cryotherapy I’d of had which is on Friday! Should I be concerned? I’m 48 with very fair freckled skin! I’ve always worn sunblock and never sunbathe! There is a history of skin cancer in my family.
