For the past 4 days, I've been suffering with a severe headache. I'm not even sure if it is a headache or something more serious. Basically, anytime I walk, or bend down, there is a shooting pain that starts from my neck and goes to my head. The pain spasm lasts roughly 5 seconds, and it keeps repeating, depending on my motion (walking or bending down to pick something up).
I must also mention that I have a chronic problem of cracking my neck, and lately, due to a stressful job, I've been doing it more frequently. It's something that I can't really control, and do on impulse (to temporarily relieve the tension in my neck).
I'd appreciate if someone can please give me some advice on what this might be.
Thanks very much
