This video was personal to me. Woke up with pretty intense neck pain on one side that I did not have when I went to bed commonly called Acute Torticollis. I was not able to get into my chiropractor for an adjustment before work, so I performed a simple drill at home and the pain went away completely and the stiffness was almost 100% gone. The drill takes you how to contract and stretch the levator scapulae muscle to reduce threat to the brain. Typically people wake up with this condition because of stress. I don't know why I was stressed but glad I could get rid of it and be able to work. Hopefully this helps.
