[/INST] Hello, Thanks for the query to H.C.M. Forum.I would come up with these possibilities for this  severe pain in the back from last 2 months, these includes.1 Lumbar-sacrum degenerative disease ( L  S  spine disease ) . Diagnosis can be confirmed by M R I and X ray L S region. 2 Pelvic inflammatory disease , diagnosis can be confirmed by physical as well clinical examination . As sometimes this produces excruciating pain.3 Osteoporosis may be the nest reason. Diagnosis can be confirmed by estimation of calcium level in blood.In my opinion consult an orthopedic surgeon and get his opinion.Good luck. Dr. HET </s>
