For awhile now my face has been getting really itchy but there aren't any bumps or rashes. After I take a shower or wash my face it does get red for awhile but goes away in a few min. I haven't used any new skin care products or eaten anything different so I don't know why this is happening and what I can do. I have been eating more shrimp lately and I've also been eating more protein bars and dairy so I'm wondering if that could be the cause. I just got my period for the first time in a few years after ammenorhea so I'm wondering if this is hormonal or stress related. I've never had eczema and my skin is usually perfectly fine.
