Rhematology condition. Right direction.

Hello Doctor, My mother has some rhematology condition. Her all joints having severe pain. Doctor said she needs to keep herself at bay from any pain medication because that was not working in her body. Heart medication, thyroid 25 & calcium tablets is on. Her diabetes level is 100/125, BP level 75/110. She has been treated with Dr.Hrudananda Mishra (cardiologist) Cuttack, Odisha. He suggested to check with some rhematologist for your joints pain. In the past, she took couple of steroid injection as per local doctor prescribed. Then after for 3 years, no pain found. Then after pain bounceback to both the knees, hands, wrists, shoulders joints. This is need of the hour revered Doctors. Please suggest me right direction. Thanks & Regards Pramod
