I Have Been Suffering From Ankylosing Spondylitis In My Lower

I have been suffering from Ankylosing Spondylitis in my lower back since 2008 but after many tests doctors diagnosed it in 2011. Since then I have been under consultation with a rheumatic specialist. I have been taking salazines along with pain killers. The pain was around in control for 1 and a half year. But from last year the pain got an aggressive mode. I can't even stand steady after getting up in the morning and after I get up from chair, sitting from half to one hour. I also have HLAV27+.

P.S: I have smoking bad habits and I also don't go under any physical exercises as my doctor suggested.
