The diamox is working! It has relieved the pressure in my head and ears, and to my surprise and great delight has also helped with my neck. This is so amazing! I am so very grateful to you Dr. Diana. I still get some tingling sensations, but that is much preferred over the head pressure. For as long as I can remember there have been issues with pain that mimicked sinus pressure, yet scans and exams would show the sinuses to be ‘remarkably clear’. And no one had an answer or even an idea on the cause. Now the answer is clear to me. Thank you again for your persistent research.
