Found my own solution

Going to get straight to the point. Typed in all my symptoms and landed here. I’m not a medical professional and can only hope this medication I stumbled across can help someone else. Betahistine is what I’m calling my miracle pill, hopefully it can work for you. If any of the following experiences apply to you it might.

It started with what I’m told is likely ocular migraines (no official diagnosis). Flashes of light in one or both eyes, similar to lights passing through a treeline in my peripheral vision. A couple months later I had a sudden onset of vertigo. First time. This was accompanied by fatigue, memory loss, inability to focus, brain fog. I prided myself on my memory and was struggling to keep it. I started taking the betahistine -I requested it from my doctor after my lucky stumble into it. I was finally able to function. Note- I was also told by doctors I could be suffering from multiple things at once but the betahistine cleared my head, and fast!
It was only 4 months in when I found it but the very next morning I felt amazing! Not even close to 100% but it gave me hope.

For years I’ve had earaches, accompanied by headach, sometimes numbness or tingling in the face or head and for years I’ve just gone on with my life, no Dr. able to help, too often feeling unheard or believed. I’m not a stressful person and have never associated any of what’s going on to stress or depression, just stuck it out. Seen 2 ENT’s, waiting on a neurologist still. Who knows, maybe a diagnosis will come yet. ..?
Main point to this longer than anticipated shout out is betahistine helped my brain fog, loss of memory and gave me my focus back. The side effects are minimal but unfortunately beta blockers aren’t for everyone but doesn’t hurt to try. Hopefully your doctor’s will at least agree with that. Good luck!
