Hello Sir, I Am Having Pain In Pelvic For The

Hello sir,
I am having pain in pelvic for the last 7 years. I have consulted many doctors (including orthopedic) but my pain was diagonised as ankylosing spondylitis 2 years before by conducting blood test in which I was found hla b27 positive. Now and then I always suffered with pain in my hip. Doctors told me to do exercises to get relief from pain and dont use medicine.. So, I use to do exercise everyday but for the last 15 days pain is excruciating and I am not able to get rid off this.. Please help me and please tell whether this desease can be removed for ever. And if yes, how it can be done??
