I'm a 57 year old woman with Fibro and joint pain, arthritis...Thursday night I had to sleep on the floor awaiting the arrival of a new mattress replacing my waterbed, very uncomfortable all night woke up in pain. Got the mattress first thing and made the bed which then made my hands and arms hurt even more. Not much later I was hurting pretty bad all over; neck, shoulders, arms, hands, back, legs and a migraine and couldn't wait to sleep on my comfy new mattress. Turned out I had an excruciating night of pain sleeping on it and can hardly move today I hurt so bad despite the medicine Hydrocodone I took. What has happened to me? The floor alone? Purchase a wrong mattress? This doesn't seem right to be in so much pain all over simply for what I've done.
