Sunshine! It’s so much fun to play in the sun! But sunburn is no fun at all. Almost all of us have experienced sunburn at some point. Pain, soreness, pinkness/redness, skin flaking, sometimes even swelling, blisters and ulceration. Some people also feel like they have the flu – you feel like you have a high temperature, can have chills, nausea, headache and feel tired or weak.
