 [ Symptoms ] what i should do to get rid of eye puffiness [ Disease ] that is kind of weird is not it unfortunately only a physical examination can help figure out what those marks are from your description they almost sound like stretch marks but the shin would be a very odd place to find stretch marks i would suggest you make an appointment with your primary care provider to get them looked at i do not think they are the hallmark of anything serious but i am not a doctor a physician nurse practitioner or physician assistant might see these marks as a sign of some other condition that is why i am suggesting you see a doctor this is not an emergency situation but it is worth getting checked out i realize this answer is unsatisfying but i hope you find it helpful
