i am glad i stumbled on this site i have had this pain at night for 4months i have only had 2 nights pain free so far. it starts about 4hrs after going to bed it is my back and particularly my right side. i have gone to the doctor several tests only to be told IBS, no pain releif helps, treatment for IBS does not releive it. when the pain starts it feels like i am paralysed and can't turn to releive the pain i have to prop myself up with pillows this does give some releif. when i get out of bed in the morning i have to lie side on then sit for a few minutes before getting to my feet it takes about an hour before it feels easier. after reading how long some people have suffered this i am concerned as i am an active person and have cut back on various activities to get some relief but that has not happened if anything the pain is getting worse. if anyone has any answers or solutions please post them. just out of curiosity has anyone tried alternative medicine that has given any releif.
