First of all, never look up your own symptoms on the internet. Sounds to me like SCM muscle strain and bilateral would not be unusual with reading and sitting at desks, looking at monitors ect. After reading your post again it sounds as if the pain is superficial, er outside your skull, if that is the case try some NSAIDS like advil, motrin etc. I assume you are young and in good shape otherwise with no other s/s so if there is no facial drooping or other you will at least live long enough to graduate ( jsut kidding). The popping you back/shoulder thing can cause nerve damage which would be consistant with "shooting pain". My advice is to chill out, relax. I think you will make it.
