None of them is not good option except for surgery untill othervise is proven!! ;I think!

If you want, I can show you the patients from the real life .....
Just After surgery, all my patients are improved suddenly and... they are giving up their medications after first week of surgery.. please dont discuss the benefit of medşcations
This is not my area of expertise so not sure my comments are valid w.r.t. your question. However I can say from my experience in cancer field that ketorolac tromethamine is more potent in malignant bone pain c.f. other NSAID's, particularly when given via the parenteral route. Unfortunately it also seems to have a 5-20 times increased likelihood of causing serious GI side effects c.f. other NSAID's. So all NSAID's are not created equal efficacy wise in cancer pain, but there is a price to pay with the side effect profile. When cancer pain is very severe I use ketorolac or parecoxib sodium short term, not ibuprofen.
Having said this, I would not necessarily ketorolac in other clinical settings as this is not my field. So the context of clinical use is the key here, not necessarily the drug alone.
