hello, about 45 minutes ago I had a strange event. for about two hours before that I felt very weak and my normal chilli self. at one point I gave my thighs a good massage as my whole body felt slightly sore, like every muscle in my body had a good work out. about 2 hours into feeling this way it started getting more intense, very cold, weak enough to try finding a comfortable spot on the floor, also a couple times walking around the house I got head rushes where my vision and balance got very blurry I could not get comfortable on the floor and decided I wanted water, started going up the stairs and the dizziness intensified, I felt I had to grit my teeth and really push to get up the stairs, when I got to the top I immediately say down and layed on my back, if I did not I would have fallen, for the next 4 or 5 minutes, well it seemed that long, most of the muscles in my body tensed right up, especially my hands, forearms and my calf muscles. I could barley open my hands out of a fist, took much energy and when I got them half open, I had to push my hands on each other to get them open, then everything started to go away and I was left with just coldness, now the last 45 minutes, i haven't felt dizzy again yet and i'm my normal slightly chilli self. I don't know what to think can you tell me
