head buzz/electric impulse

Hi, whilst I am awake almost every few minutes I feel a very short buzz/electric impulse/mental twitch it feels a little bit like an electric shock or the feeling like right before you orgasm, but much less intense and much shorter it is very difficult to describe but i am trying my best. This has been happening for almost 2 weeks and it happened to me long ago but only a few times and I didnt read much into it. However, now this is happening almost all the time when i am awake and I have found myself wanting to sleep much more than usual i sleep more than 12 hours a day now and last week I didnt want to wake up and spent almost 36 hours in bed. Also, whenever my senses are stimulated especially touching something cold or hot or rubbing my hands or face etc this induces the buzz i get. Also, sometimes i get shooting pains which feel very hot in my leg and sometimes hands. Could this be something related to my nerves, should i get a brain scan or MRI? thanks

Hi;

   Odd sensations to be ongoing. Are they still occurring as of Sept. 9?
   Seems a Neurologist should be the one who determines whether you should receive an MRI.
