What Causes Numbness On The Arms And Legs With Chest Pain?

I m a 22 year old male, 2 days ago I woke up and as I usually do felt some kind of numbness on my arms, because I have the bad habit of sleeping over them, but what was rare was that one of my arms couldn t get of the numbness, then I started to worry about it being something like Deep Vein Thrombosis because I heard of it, and started to worry about having a cerebral embolism. Short after that I felt a little bit of pain on my chest followed by a feeling of drowsiness I never felt before. After that shortly I started to feel strange in my foot and leg, and my hypochondriac self assumed it must be some kind of embolism going to the leg, and now I felt something in my arm... and I m going crazy, because I don t know if take this seriously or if it is just my hypochondriac self been hypochondriac. Thanks
