My back hurts every time i take a breath in. i get bad pain in back. it also hurts when i move my back what could i do to make it go away. could depo provera cause this ?

Proper management would require a proper assessment. That would start with a history, exam and tests if needed. It could be anything from pleurisy to a problem with the muscles of bones. I can't link a depot shot to this as a side effect, It sounds worthy of a checkup.

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. If your symptoms are not improving, it would be prudent to see a doctor. Wish you good health!
