Get the MRI in addition to your Xray.
I buried two friends, who took some of the meds, for back inflammation problems, similar to Celebrex, that blew up their hearts. One was 73 and the other 49.
Best to treat the cause of the inflammation, once known, with meds that have been around for decades.
Indomethacin, is one of the safer ones.
Blood work, to check liver/kidney function, is essential with many meds, as is being aware of stomach irritation.
Hope you have good Doctors, as not all are top tier.
80% of our family are in the medical sciences, the rest are lawyers and teachers.
Hope they did a complete lab workup.
