A rash receive some cream from the store. You may of itched it at night and you didn't know. I do that adjectives the time.
Eczema
I had them once and my dermotologist told me they be Granuloma Annulare and he took liquid Nitrogen and sprayed them. Mine did not itch neither. They only look bad and they are red knotty nodules. They come and go and I do not know what cause them!! He stated small children usually get them and I enjoy been to 5 top dermos and they said ezcema, dermatitis and etc..Try Zinc Oxide on them...
