From the photo, the bumps on the back of your neck could be due to folliculitis (inflamed hair follicles / acne at the hairline) which commonly occurs due to sweating, friction from collars, recent haircuts, or bacterial irritation of hair follicles. Another possibility is urticaria (allergic hives), especially if the bumps appear suddenly, itch a lot, and come and go within a few hours. This can be triggered by sweat, heat, pressure, or an allergic reaction. Helpful tips: • Avoid scratching the area. • Change pillow covers regularly and maintain scalp hygiene. • If bumps persist, spread, or recur frequently, it is important to get it properly evaluated.
