I have had a constant headache and clogged ears for the past 8 months, with ringing in the ears and throbbing in my head when I lay down. I only get nasal drip after eating. I have had antibiotics, steriods, a root canal, ct scan and mri - all negative. I am using a TMJ mouth splint and going to the chiroprator 3 times per week, and still no relief. I am scheduled to see a neurologist next month.
