The tips of my ears burn, and it lasts a long time, like hours. Why is this hapening?

hot around the ears,

Thanks for your question.  This is not a typical symptom of high blood pressure.  When people get upset they often become flushed, which is caused by a widening of small blood vessels in the skin, especially the face.  Some people get more flushed than others, and some people manifest this same reaction in their ears.  The length of time this lasts can be variable.  Sometimes, in cold weather, if you vigorously rub your ears, it will cause this same reaction, which in this scenario is beneficial because it will keep your ears warm. 

Though this does not necessarily mean that you have high blood pressure, a person's pressure can rise if he/she becomes upset.  If your pressure has not been officially checked, I suggest you make arrangements for a reading by a nurse or physician, preferably when you are not upset.

Best wishes.
