My mother is having pain in her lower back side (right) for over 5-6months. If she stands for long/does a lot of work, her pain increases but if she is relaxing, the pain reduces but not completely. I'm not sure which doctor do I consult. Can you help me with this? Previous medical history: She is taking medications for having severe stomach ache and unable to consume spicy,salty or tangy food. I took her to AIG, we did xray, endoscopy and colonoscopy but everything came out good. Even with medications, she is unable to eat anything spicy, salty or tangy, she is just eating bland food. She is taking medications from Jan.
