If you have an idea on what goes on in the data, detrending is not inherently statistical, just a trick to get you something like a sample - a realization of a stochastic process that is (in some sense) stationary, so at least its mean does not change. share | improve this answer. edited Jul 31 '11 at 19:44.
Rod_Moser_PA_PhD responded: No, you did not likely damage your ear, but pain in the mouth/tongue can cause pain to be neurologically referred to the ears (due to nerve pathways). Canker sores (aphthous ulcers) can also cause tenderness and swelling in the lymph nodes, and this can cause referred ear pain as well. I can't examine your ear to be sure, but I suspect your ear is just feeling the pain originating in your mouth. inboston responded: Thank you very much for the medical reply to the person with the canker sore on tongue. I have similar situation, with partially blocked ears and ear ringing.
Canker sores can be very painful! The exact cause of canker sores is not entirely certain, although several different factors including stress, certain spicy/acidic foods, or vitamin deficiencies can be associated with them. They are also associated with some autoimmune or gastrointestinal conditions such as Crohn's disease or celiac disease. Canker sores typically resolve within a week or so, although aggravating factors such as spicy foods or mechanical trauma can make them take longer to heal. The fact that your canker sores have persisted for over 3 weeks is an indication that you should return for evaluation with either your dentist or your oral surgeon.
