Since going back into education last year I started getting a tingly, trickle sensation like water going down my forehead, I can go weeks without it some time and at others have it a few times a day. Lately I have studied and worked alot but I am getting that sensation in other parts of my body such as my hands and my left leg (leg only started today) I'm not sure if it's to do with anxiety which I suffer from or what.. I also have had on and off indigestion for a few weeks and get it a few times a day, I only mention is as I don't know if they are linked at all. I might sound mad but I got cramp in my left arm earlier when typing on my laptop and my little finger bent and I couldn't bend it back to normal for a few seconds, I tried using my other hand to straighten it but I couldn't and had to wait for it to pass which it did after a little while.. worried I'm a hypercondriact!
