It took a while and I was in a major medical center...started with primary, referral to a very busy ENT. One of them did temporal CT after I kept pushing for answers. That showed the diverticulum but the doc didn't think that was causing the problem, so it was kind of dropped by the specialists. So my primary referred me for an mri. (I have a great primary.) I was also seeing a spine neurosurgeon for some other pain, and he referred me to a brain neurosurgeon because I was having increasing pain in the back of my head. By 8 months in, I started having debilitating migraines. I'm not sure if that was from not being able to sleep at night or the pain from the pressure from the growing diverticulum. The brain neuro did a brain mri/mrv/mra and said he could do a procedure to fix that but didn't think it would solve the pain I was in. I agreed to an angiogram to see what the pressures were, and after that I agreed to have the stent and coil done to fix it because I couldn't keep going as I was. Once I recovered, the pain has been gone as long as I don't overdo it, but even then it's mild. That also solved the noise and blocked ear feeling. He said that was caused by turbulent blood flood in the diverticulum which was right behind my ear, so pressing on parts of the ear. I'm grateful I had great insurance bcs all of that was very expensive.
