Terrible and if I could keep it more controlled on an even basis I could stand it more easily. So, instead of taking 2 tylenol 3 every 4 hrs. Can I take 1 every 2 hours to keep the pain more levelly taken care of (to a degree). I am old + have severe Deg.Disk disease and the pain is 24/7 & arthritis in spine also? I have no quality of life because of this. Taking the med every 4 hrs. The pain is way up and down. Thanks.
