my back also hurts when laying in bed,I move from side to side all night long.Ive noticed alot people saying they have those pillow top mattress's Im wondering if that has exagerated my back pain.since taking lyrica ive finally been sleeping all through the night,I cant beleave I was so afraid to try it because of all the side effects that people were reporting.I was prescribed it back in sept and did not start to take it untill feb.I havent gotten any foggier than i already was,I dont think ive swelled up but I am eating like its the last supper,but my nerve pai is remarkly better,and the epidural shots have helped my leg and hip pain ,so I guess this stuff really is different for everyone. have a good night every body hope every has a painfree night marywoo
