Hi. I'm A 53 Year Female With Chronic Lower Back

Hi. I'm a 53 year female with chronic lower back pain. I had juvenile rheumatoid arthritis as a child. In the last year I've noticed my sides at my upper part of hips is sore to touch. Either from muscle spasm or back changes I have a slightly uneven gait. any heavy lifting or the wrong move cause pain in my lower back. I can feel a bulge in my lower back for weeks. It hurts. Who do I see about this
