I've been suffering from Ankylosing spondylitis since past few years and due to the financial condition of my home, I haven't been able to treat my this condition properly. Since past few days, I'm dealing with a tremendous amount of pain in my right hip. I'm having much trouble in climbing up and down from the stairs and barely can stand up on my right leg after a continuous sitting of 2-3 hours. I've tried few painkilling medications but none of them worked till now. My Exams are starting from 10th June, any medication which can I take which at least can give me some temporary relief during my exam period?
