Strained my neck/shoulders

Serafimangel

Hey, I did the 3rd level of the 30DS and managed to strain my neck and shoulders. Wont do it for a day or two. Problem is, I've got sinusitis which im on antibiotics for and so I just have a constant headache. Are there any streches I can do to ease the neck pain. I cant use painkillers or the muscle patches as I'm on the antibiotics and sudafed sinus stuff.

Any ideas? my head is killing me.
