so recently ive had these emerge all over my neck and arms:image

I thought these were just mosquito bites but im now worried as to what it is. Could it be allergies?

t does look a lot like an allergy. Once, after taking an antibiotic that I am allergic to, I had the same kind of spots all over my neck, back, and arms.
Try to observe if this occurs after eating a certain type of food or taking a certain medication.
