Dear patient First of all I would like to know your age. Back pain since 10 years indicates chronic nature. You history suggests arthritic nature of back pain which is worse in morning and improves as day passes.if you are of young to middle age kindly do your blood level of HLA B27 to rule out ankylosing spondylitis. I would like to advice radiograph of spine. Kindly get this two things done and we will come to diagnosis and help in planning treatment.
