I was hospitalised with vertical double vision, droopy eyelid and loss of sensation in my right hand for a few days last year. Spent a week on a neurology ward and woke up one night with every back functioning as it should. Had numerous tests for myasthenia, strokes, CT and MRI scans etc. and nothing was identified. Same thing happened a few months ago too and the neurologist asked if I'd had any migraines recently and I remembered I had in advance of this stuff happening. Thinks I suffer a severe migraine which causes inflammation in the nervous system causing these symptoms. They're absolute rancid things and I met a few other people with similar symptoms to what yourself and I endured recently. Keep a diary of things that happen as until the neurologist mentioned migraines I hadn't even considered that link.
