For a couple years now I've been experiencing sharp sudden burst of pain in my temple. It feels like a cramp and usually lasts about 19-30 seconds. It used to just be one or two every couple of months, but in the last week or so I've experienced 20 or so a day. And it's not just in my temple any more, it's also in spots on my arms, legs, and neck. I'm a 19 year old girl. Any ideas?
