Red spots on the neck
Good morning,
I have had these raised redness on my neck for 2-3 days. The cause is unknown. The area is sensitive to touch, but not otherwise painful. It has not changed in size or appearance in the last 1-2 days. About 4 cm below, a lymph node is swollen, tender to the touch, and movable. About 1-2 years ago, I had a mild case of eczema on my feet, which has since healed and not recurred. I am 47 years old, male, non-smoker, non-drinker, and have a healthy and balanced diet. I have no work-related stress and maintain good hygiene.
What could it be?
