I Wake Up Each Morning In Horrible Pain All Over

I wake up each morning in horrible pain all over my body and I can't seem to move. I can hardly lift my arms or legs to get out of bed. After a lot of struggling, I can finally get to the side of the bed. After sitting there for a while I can finally get myself out of bed and head to the bathroom and back to a chair in the bedroom. By then it usually eases up. It's a little more severe each morning and it takes a little longer to recover from this. Yesterday morning it didn't ease up, so we went to the hospital, they couldn't find the answer to my problem. Can you help with any suggessions? Thank you Nancy
