My mom has SEVERE pain in her neck and head from osteo. She can hardly take it. She has put up with it for many many years, but now at almost 60, she is finding it extremely hard to enjoy life and function at home and in society because of the constant searing pain. (I assume her disks in her neck are all grinding.)

She has tried strong Tylenol and strong Ibuprofen. Those don't work and are terrible for her.
She has now also tried Celebex and is still finding little to no relief. She has been taking it for 10 days and was told if it's going to work, she will know in about 10 - 14 days.

Any advice on how to help her with her terrible pain and headaches?
