Patch tests. Contact allergy would be diagnosed with allergy patch testing. Other possibilities are a fungus infection or a patch of eczema or psoriasis. See dermatologist for diagnosis and treatment.
Rash. Your rash on the collar bone could be irritant contact dermatitis due to these things you described. It could also be eczema or urticaria, triggered by anything from allergy, cold exposure, emotional upset or something you ate. It really needs be visually examined along with a pertinent hustory by an experienced physician.
