 [ Symptoms ] my ears get red suddenly is that a blood pressure issue  i work 3rd shift and it seems to happen in the early morning but happens more often now at other times [ Disease ] no red hot ears is not usually a problem with your blood pressure but it is vascular in most cases this unusual phenomenon is just a variation of blushing    warm red blood is shunted to your outer ears giving them that red appearance unlike other blushing this is not necessarily caused by embarrassment or other triggers it just happens for some people the ears can uncomfortably hot or even painful to the very least it can be embarrassing there is very little that you can do for this but since you mentioned blood pressure the use of a class of drugs called beta blockers has been used for red hot ears these are use for high blood pressure preventing migraines and other cardiac problems sometimes it helps sometimes it does not it would be up to you to convince your doctor to prescribe them for this purpose red hot ears are harmless but if you consider the problem severe beta blockers may be worth a try there are many discussions about red hot ears on webmd is ear nose and throat community board if the ear is red and hot only along the top two thirds or so where the cartilage is located and the tip of the ear or the ear lobe is still close to normal in color the problem could be relapsing polychondritis this is a very rare autoimmune disease that attacks the cartilage in the body and is not limited to the ear it can attack the trachea heart valves eyes joints and connective tissue this can be a very dangerous disease that is very difficult to diagnose as only about 3 or so people out of every 1 million ever develop the disease mayo clinic has a good easy to understand write up about it if you suspect that this may be your problem after reading the mayo andor other articles you would do well to contact a rheumatologist and mention it to himher be sure to bring up the name relapsing polychondritis as most doctors have never seen this disease it took me ten years to get diagnosed i have the same issue and i see it was suggested to try beta blockers here given that it does not seem to be an issue to be concerned about is it worth to run the risk of beta blocker is side effects to deal with this thanks for your answer hi   i have had the same problem for the past 3   5 years for no obvious reason one or both ears suddenly heats up most often at night if this happens while i am sleeping i end up with a migraine so what i do is drink a lot of water before i go to sleep   meaning i have to wake up to pee i then also douse my ears and neck with water to cool down kind of unpleasant but it is the only way
