Hi again. I ordered the cervical traction device by overnight from Amazon, and I'm wearing it as I type. So far so good. It's a soft, 3-level inflatable collar with a hand pump to inflate it. It's quite comfortable to wear. It feels fully inflated and it's definitely keeping my head up. Strangely it came with no directions at all, so I'm going to follow @sgmjohnny's advice and wear it for maybe an hour twice a day. So far there's no itching while wearing it, and I had bad itching last night and this morning that required an ice pack.

I will definitely keep everyone posted on how it's working.
