I noticed a red mark on my neck that suddenly appeared in the past couple of days. It looks like a hickey, but Im sure its not. I havent had any sexual activity for a few years. The mark doesnt hurt or itch at all. Im 31 years old, male. What could this be?
A sudden red mark on the neck that doesn't hurt or itch could be from minor trauma (like scratching), an insect bite, or a skin reaction. Other possibilities include an allergic reaction. If it doesnt improve or new symptoms appear, consider seeing a doctor for evaluation to rule out other causes like dermatitis or skin conditions.
