Most of the times the red ear will just come on randomly, I can feel it coming on. Sometimes stress will bring it in. If I'm upset. It can last for hours or shorter.
Thank you for the information

Thank you @loribmt for tagging me and for sharing those links. I’m here to learn from others and provide my story in hopes of getting some help for us. @leelou03 i have noticed the red ears for several months they switch sides, burn , and itch. I spoke to my ENT whom I’ll see again in a couple weeks and he’s never heard of it. He’s going to check into it. I will also be seeing a new skin doctor March 13 maybe she will have some input and my Family Doctor March 19 . After reading the links Lori shared I will ask the doctor doing my cervical epidural Tuesday( I have several bulging disc in my neck, but no surgeon wants to touch it after I’ve had a failed back surgery April 2023). I have a cyst on my brain and severe Tinnitus and will be seeing my Neurologist in April so I will ask him if the others don’t know. I do have High Blood Pressure but haven’t noticed it being the cause, I have Sjogren’s disease I really started noticing he red ears the day after I seen my Rheumotologist ( go figure) so I didn’t get to ask her yet if it’s got anything to do with the Sjogren’s or any other Arthritis. If you have any suggestions or questions feel free to reach out to me. Unable to work over a year , 4-5 doctor appointments a week it’s great hearing other encouragements

I go to the dermatologist the 28 of March. I screen shot the links to the information you sent. It should be helpful. Thank you again

My daughter is 14. This has gone on for maybe 5 or 6 years. It was only her ear but then moved to cheeks amd a recent bout that went down her chest. All doctors are clueless about it and chalk it up to some vasodilation. This happens daily, sometimes numerous times daily. If she has a day that it doesn't happen, she doesn't even know because it happens so often. No amount of research other than the typical causes of vasodilation and RES (red ear syndrome) have provided any useful information. Could this just be normal flushing? It is hot to the touch and last a few hours usually. It is embarrassing for her because EVERYONE notices because it just happens so quickly with often no apparent reason. Extreme activity and anger cause this but the heat, why the heat? Do you have any advice?
