I haven’t been diagnosed yet, but I have a feeling it may be MS. So I experience a lot of freezing, my legs get stiff and It’s hard to put one foot Infront of the other and I get embarrassed. But prior to my freezing I get this spasm or zap in my spine and I feel it reach my brain. Although this zap/ spasm is a couple seconds it really tires me when it hits. I have this fatigue the whole day sometimes sort of as if I ran a marathon. My face goes numb. my eyesight hurts. My balance and coordination when walking has also been affected. I have a short term memory deficit and poor concentration. I do suffer from anxiety as well.
