I had sharp shooting pain in the chest after a history of 8 years of severe back and bone pain but now I have been diagnosed with ankylosing spondyitis, and x ray revealed osteophytes, loss of lumbar lordosis and partial sacrilization of L5 vertebra. Alos i have respiratory distress, tingling in the feet at times and have been put on Saaz 500, Enzocort 6, Folitrax 7.5mg, Folvite, Lorsaid P 8 and Pregalin X SR75. Are these medicines indicative of spine cancer
