Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
severe back pain can be caused due to causes like sitting in wrong posture for long hours,
muscle strain or ligament tear, bulging or ruptured inter-vertebral discs,
Osteoporosis,
Osteoarthritis, Scoliosis, disc degeneration etc..
I would suggest you to consult an Orthopedician and get evaluated and he can advise you investigations like x rays, MRI SCAN, CT SCAN,Nerve conduction studies, blood tests to rule out the exact cause of the pain and treat you accordingly..
He can advise you to take antibiotics like Ibuprofen, Naproxen etc..
He can also be advised to take muscle relaxants like Chlorzoxasone..
He can also be advised to apply topical pain relieving gels like Diclofenac..
He can also be given injections of analgesic, steroids and local anasthetics..
Physiotherapy and muscle stretching exercises can be advised..
He should also get massage with medicated painkiller oils to relax the muscles..
Avoiding long hours sitting and standing and exertion..
Hope this information helps..
Thanks and regards.
