Hi, I M 50 Years Old Women And I Am.suffering

Hi, I m 50 years old women and i am.suffering from movement block on all the major and minor joints in my body. I have visited the doctor and he prescribed me some nsaids but the problem is that whenever i took the meds pain dimished and when i stop taking a single dose the pain reappears. My vit D tests comes normal and i didn't have joint pain issue previously. Is it rhematoid arthritis? Please guide me what should i take to go further ?
