I am a bit worried. I am 32 years old and I have never had any serious problem with my health. I also try to keep my body in good shape with a lot of exercise whenever I can spare time. But, several days ago I have noticed a couple of red blisters on shins. What could that be? They are not painful, but they are a bit itchy which makes me want to scratch them. Is a visit to a doctor something I must do right now or should I wait for several days, to pass on its own?
I would see a doctor immediately. Not because I think that you have some serious problem, but because you should finish with that quickly. There is a possibility that you have some infection that can be taken care of easily with medicaments, so there is no need for making a delay. Red blisters on shin are not that dangerous, but why keeping them on your legs, even for a day or two?
