Good evening, Quick question on the use of cervical collars / supports when performing 'home improvement' projects. I have CRPS, a loss of dessication in the cervical spine discs, a loss of all curvature in the cervical spine, and radiating pain at the C1/2 area due to a whiplash-type injury. There is no damage to any of the discs (just the fluid degeneration). I've just started your book, and was curious about your opinion on cervical collars supports? Do they help to hold the neck in a proper position while working bent over, or do they cause more problems such as locking you into an improper position? I'd like to be able to do some projects around the house without hurting so much. Thanks!!
