Hi, thanks very much for your reply.

I definitely do have a forward head with regards to posture and have had for years. I am a PhD student and spend all of my time at a computer or doing close work hunched over circuit boards. The only thing which triggers headaches is when I go to sleep, I have tried different positions and pillow heights and they help slightly but don't stop me getting the headaches. The only thing which seems to make them go away is to stand up and start my day - then they will start to fade.

I have never experienced any aura but when the headaches are really bad sometimes I can see my vision pulsing with my heartbeat.

Can you recommend any exercises to strengthen the deep flexors in the neck and help to alleviate a forward head carriage?

Philip
