<s>[INST] For the past three days I have experienced pain in my back on both sides feom the lower back to upper middle back. Ive taken ibuprofen but the pain continues. I have not had an injury and the pain begins as a dull pain and becomes more intense. Do you have suggestions on what could be causing this? [/INST] Hi, In my opinion I think it is not a back pain due to bone injury it may be pain due to renal colic, stone or gravel it may show painful urination and sometimes referred pain to gonads otherwise it may be a kind of muscular spasm that is relieved by topical gels, physiotherapy, massages and hot commendations are recommended for now you may increase your water intake and ask your physician for some investigations for proper diagnosis.
