I am on co codamol for my back and when its really bad take diclofenac but have to be careful cause tramadol and diclofenac send me loopy (yes more so than I am now, it is possible) and they send me to sleep so I tend to stick with the co codamol and just put up with the niggliness that remains, as my 2 year old would demolish the grove let alone the house whilst I was zonked. Its only really the last week or so that they have played up but I did try to cut down on my pain meds, (big mistake as the week before my monthly my back pain intensifies ten fold and yes it appears its that time(That may sound a bit vague but with PCOS I never know when I'm gonna get one til I get the symptoms or it just happens). I think I will habe to go and speak to my GP and see what he can suggest.
