I am a 59 year old male. Past medical history of controlled hypertension and cervical fusion C5-7 in 2004 for spinal stenosis. I was doing fine until about 7 months ago. My house was being painted and the painters used a very strong smelling lacquer on the woodwork. I have no idea if this has anything to do with the problem, but it coincided with the onset of my symptoms. I developed vertigo. I was first diagnosed with BPPV and sent for Epley maneuvers. When these didn't help, I underwent a video nystagmogram which was read as normal. The symptoms persisted along with intermittent headaches. General lab work including workup for autoimmune disease was negative as were MRIs of the brain and neck and carotid dopplers. A neurosurgeon recommended a epidural steroid injection which relieved the headaches as well as some visual problems I was having, but had no effect on the vertigo. Actually, the vertigo morphed into more of a feeling of dizziness with my head swimming. There was no nausea or vomiting. Another ENT suggested vestibular migraine, but the addition of nortriptyline did nothing. Lying flat my symptoms are almost gone. Sitting up my head spins but I can tolerate the symptoms. However, standing and walking are intolerable. I was off work for a few months but after some vestibular rehab, I have returned with limited success. I've also tried acupuncture and gentle cervical manipulation without success. I fear I will have to retire. No days are good, but some are worse than others. Somedays I have headaches; others I do not. My meds are unchanged and include Losartan, atenolol, HCTZ, and Simvastatin. Any ideas?
