Earlier tonight, I started feeling quite lightheaded after some moderate physical activity. Gradually, this turned into a heavy feeling, coupled with deeper, more frequent breathing, as if I were running. Eventually, I decided to lie down. Once I did, my fingers and feet started tingling and going numb. This crept up through my arms and legs, reaching my torso. At that point, my legs started to go cold. I got a cover, but it didn't help much. I also became clammy, and my boyfriend said my face became pale. That's when I started feeling numbness around the edges of my face and on parts of my scalp. It never progressed past this point, and seems to have reversed. However, there was a period of about 20 minutes where I was doing better, but kind of stuck with what felt like poor circulation. My hands and feet were still kind of numb, and started to ache a little as if blood flow had been restricted. Now, I feel more or less normal, but my muscles are twitching and spasming in random places, especially in my feet and legs, my legs also every once in a while start to go cold again, my thumbs still feel a little numb, and there's an ache down the outside of my left calf that comes and goes.
I took a supplement that I've never taken before today, but none of the ingredients are anything that I should be having a reaction to. This happened immediately after sex about 9 hours ago.
