Good afternoon. I am trying to get some help for my 75 year old mother who has had pressure in her head when sitting or standing, ringing in her ears, lightheaded. She originally had spikes in blood pressure but that has been brought under control with medication. This has been going on for 2 1/2 months and she has not been able to get relief. This may be a coincidence but the symptoms that she has started after she received a cortisone injection in her hip. She has been to her PCP, cardiologist, ENT, and a neurologist. She has had blood work, CAT scan, EKG, MRI, stress test, etc… and the doctors say that they have nothing to go on. The only thing that we saw made us think was the MRI indicated that she had some inflammation of the mastoid bone. Can mastoiditis cause these types of symptoms and how should we approach a doctor to consider this? Thank you.
