My symptoms are mostly from the neck up. Dizziness, sensory problems, eye focusing problems, cognitive issues, anxiety, disassociation, and the occasional bout of IBS. And non-allergic rhinitis, which I'm convinced is due to constant low grade hyperventilation, something I've done unconsciously for 20 years. I've had mild POTS (my standing pulse is high, which I'm sure is the cause of my hyperventilation) for about 20 years which started with an infection. But its impact on my ability to do things using my body is close to none. My body does not feel fatigue. I can exercise. In fact brisk moving around helps my head symptoms, which I think is because the muscle pump gets blood up to my head. My doctor sees a lot of patients with POTS and CFS (which I don't have), and the moment I told her my opthamologist told me my eyeballs have tremor (yes...my eyeballs - not eyelids, EYEBALLS! - have constant tremor!) and also the fact that alcohol helps a lot of my symptoms, she suggested I have autonomic activation (said she sees the eyeball tremor in some of her patients) and prescribed me Propranolol. If I only have head symptoms and hardly any body symptoms, can a beta blocker help my head symptoms? Can my POTS be causing the head symptoms without much impact on my muscle strength and body stamina? Hey I'll take the Propranolol if it will help my head stuff, I just find it hard to believe. Does it help with anxiety?
