Today I'd noticed a sort of tingling/burning pain in my left leg. This isn't exactly new and so I hadn't really thought about it. But I was just sitting at my desk and this one spot on the top of my thigh just started pulsating fairly violently. You could actually see it moving. I checked my pulse in my neck as this was happening and it was a little fast, but not nearly as fast as what was happening in my leg. I had gone to get a checkup today and my diastolic pressure was a little higher than usual, but no one said anything. Now I feel the same burning/tingling pain, but it feels more localized to that area. I'm trying to notice any changes elsewhere, but I know that the stress of focusing on finding things that are wrong will just lead to me finding something. There is what I feel as pressure and a little bit of pain at the back of my head at the base of my skull and down my neck a ways, but I doubt that's related. My pulse is fine now, but it was just incredibly strange and I have no idea what it means.
