So I am 16 and today I went out to do some walking. I walked 6.5 km (4 mi) and then I went home. Then I started to feel a little dizzy. I went to sit at my computer to watch something on youtube. Then, at a point, I felt my hands were a little tingly. It was not very bad and it lasted only 2 minutes, but I freaked out really quickly fearing I have a stroke. I calmed down after a while but I sill fear I had a stroke. Anyone help? :(
