instruction: hello doctor I woke up this morning to see a small red line or vein on the top of my left breast I had a breast check up and mammogram months ago which was clear is this normal what is it
output: hello this does not appear worrisome to me this appears like erythematous lesion due to inflammation this has probably occurred due to some trauma like due to pressure of folds in clothing or bed sheet or lying over the chest also rule out possibility of some bite or nail scratching if this is generalized and also present on the other body parts then may be related to some infection so usually such single visible vein is not significant it should settle in a day or two but if continues to persist or increase in number or any other symptoms like swelling pain fever appears then will need examination or investigations at present does not appear significant or serious issue hope this helps you and get back if you have any doubts
