Itchy swollen ears while very early in pregnancy

[burgandyfaye]

I think I'm about 3-4 weeks pregnant (not confirmed on this yet).  About 1 week in my pregnancy, I started this itchiness on top of both of my outer ears, then itchiness spread to the entire ear in a week or so, then it spread to the back of both ears and about 1 inch down from my ear lobes.  Now it's been two weeks, my ears are red, swollen, hot 24/7 but itches from time to time especially when I eat certain fruits and nuts, then every day from around 10pm - 5:30 am, during this time, I have unbearable itch.  And this is only happening on my ears, no where else on my skin has this itch or redness.  The outer rim of ears have some dried skin peeling scabs.  But last night, the itch went to the back of my neck by the hair line. When it itches, I can feel tiny bump on the skin then it goes away afterwards.  I don't feel any itchiness or pain in my ear canals and per my doctor, they are fine.

I have never had this condition before and no skin conditions during my first pregnancy 2.5 years ago either.  I have checked with my primary care and they said it's just a rash and told me to apply topical cream.  I don't want to apply any topical cream that has steroids or antibiotics.  Not sure what natural remedy can help and safe during pregnancy.  I am hoping this is pregnancy related and it will be gone after first trimester.

I am concerned.  Which health profession should I seek further help from?  Will this affect my baby?
