I have 3 herniated cervical discs and C7 radiculopathy. I haven't really thought of it before today, but I think I'm going to rig up an emergency traction device with a towel, rope, and a quick disconnect. Not the safest thing in the world, but in a pinch, it beats pain and muscle atrophy if I jack up my neck in a SHTF scenario and I don't have access to prescription refills or my tried and true traction device.
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts. Nuts and dried meat are two of the easiest off-the-cuff meals. Canned food has a lot of water that is wasted during the cooking process. Stay away from heavily flavored or salted nuts. The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
