I started getting these itchy small bumps on my neck and chest a week ago.  I have been putting calamine lotion on them, which helps the itching and I have taken Benadryl twice.  At first I thought it was from planting flowers last week and touching some weeds, but now Im thinking maybe it is a food allergy.  The only thing I havent had any new food items.  One of the weeds I picked up looked different so I immediately put it in the garbage and washed my hands.  Maybe I touched my neck.  I dont know but the itching is driving me crazy and the bumps are increasing in numbers.
Hello, Thanks for the query to Chat Doctor. Forum. This is some sort of allergy due to weed or planting of flowers. Due to antigen antibody reaction there develops itching first at contact site. If person is prone to allergy and oversensitive to particular allergy this type OS symptoms appear. Local applicant will only soothe the site of contact. For systemic allergy (all over body) , you advised to take potent antihistamine as fexofenadine 120 or 180 mg 2-3 days. Steroid tablets 2-3 ONLY, one in time will give you relief. Good luck.
