Hi, Dextah
How did your back pain start at beginning? Any injuries? How is your movement like at moment? Any pain when you bending and doing things? When you start doing things, back feels better?
Have you try doing some aerobic exercises like walking and cycling? If you haven't try some of these exercises.
Also try some relaxation techniques, slouch if you feel more comfortable and relaxed, standing with your stomach relaxed as well.
Get me informed how are you getting on, if above seems help you, I can explain more to you.
