This question isn't about myself, it's about my father. Just recently today he had severe muscle spasms in both of his arms and experienced a severe headache almost instantaneously and without warning. He's doing fine now, it's been about 30 minutes since it happened, I'm not sure what the cause was, and I'm still baffled. He has diabities and I was thinking that had something to do with it, but I didn't want to rule out them being symptoms of a stroke as he had similar symptoms to that. He wasn't really doing much at the time, just sweeping the floors, could you please tell me what happened?
