Lately, I was noticing my skin to be somewhat flaky. In the last two weeks, the skin behind my ear is coming off, there's a slight swelling right under it. I can't locate any specific reasons which may have triggered it. It's almost like this skin is melting off. Today I noticed a somewhat similar pattern on the lining of my navel. I am allergic to metal but I haven't work anything per se for the longest time. Please suggest what to do.
