This post seems a lil bit old. Can we continue again? Dear, I hope you have bought your desirable mattress? Can you tell me which mattress are you using currently? Well my father was facing this same issue, doc recommends him to change his ordinary foam mattress into Hybrid Gel mattress, and trust me after changing mattress he feels quite well and his pain is reducing day by day, If you are still facing the same issue I suggest you must check on
BiteMe, because I bought mine one from there.
