If you are having a migraine, ice on your neck will help, as will hot coffee. Both will help constrict the blood vessels that are causing that pounding. If you are like me, the migraine causes you to tense up and that makes the muscles hurt more which causes more tensing up and hence a worse migraine. So some muscle relaxation might help, too. Good idea you had to do the stretching. Maybe you can stretch your calfs and that would help your shins? I really have no idea if that is even a reasonable thought. Probably couldn't hurt, though.
