Answers:    It is possible that you could have some tension in your trapezius ( major muscle on back of neck), when this and surrounding muscles get tensed and knotted it can raison d`¨ētre headaches and neck aches. Try and bring back a massage (Hot Stone Massage is best) and the therapist will let you know if you are tight or knotty. this is a adjectives cause of headaches.
Every time I get a headache it means that I am dehydrated. Start near drinking a lot more water over the course of the day and see if that help.
