I have been on Oxycotin 10mg 4 times daily I have degenerative disc disease along with spinal fusion in L4 and L5 there are 4rods and 8 screws in that area. The disc above it L3 & L2 are missing. I would like to know if I ask to switch to Opana ER would that help in keeping the pain down and also make it to where I do not need to take pills every 6 to 8 hrs. I would like to take less in the way of pain killers yet get the same if not better relief.
