Hi there stephanie.
Snickers happens to be an all-time favourite in my household ;-)
In dermatologgy we are a very visual subject & as such would appreciate if you could post a clear digital image of the lesions on this web-site .
Having said that & read your history et al, it is very possible that it is a reccurence of your childhood eczema
...a condition we refer to as atopic dermatitis
It is very possible that you have a peanut allergy
as peanuts are an integral part of snickers'.
For the moment a topical hydrocortisone-fusidic acid
combination cream applied twice/daily should suffice. But, i strongly recommend fixing an appointment with your allergologist & running a few tests to ascertain what substances you are allergic to.
Good Luck & wish you a clear skin!
