Sleep is not sleep

Last night got about 5-6 hrs sleep. woke up maybe 14 times. Everytime I turned. stretch legs caused knee pain. Then to turn body strained lower back and neck. Zero arm strength meant I turned full body like an overweight walrus. Add in flu like head and overall aches. Multiply by 14 = a bad night. It is now 5 am. Sometimes if I stand I get temporary relief. But standing up from bed is itself a major effort and I feel weak and unsteady. When will it end.
