I am seeking help because I have a weird red line that appears on my forehead usually in the middle, it has happened 3 other times in the past year and this is the 4th time but this time it appeared slightly to the left of normal and has a curve in it and is up higher. This led me to raise concern that it could possibly be something serious. During all the instances I was just doing normal things, I wasn t stressed or doing any strenuous activity or hit anything. Please help me better understand what is happening
