<s>[INST] Thanks. I have a variety of symptoms but the worst is my back. After standing/walking for about 3 to 5 minutes, my mid to low back stiffens making it difficult to walk. Eventually, I bend over at the waist like a shrimp to relieve the stiffness. After this is extreme fatigue. If I clean house for more than 15 minutes, sweat pours off my face and head. If I stop at several stores and then maybe do the laundry (in basement), the next day I am so exhausted I can t get out of bed. These are the worst symptoms. I also have incontinence and my urine suddenly began to smell awful about a year ago. I don t know what kind of doctor to seek. Rheumatologist? Geriatric? [/INST] Hello, You should consult rheumatologist. If not relieved then possibility of poly arthritis needs to be considered. Rheumatoid arthritis may involve small joints and early morning stiffness in joints, do you have sucChatDoctorplain? Ankylosing spondylitis typically involve spine and hips with other large joint also. There is reduced chest function in this disease. Stiffness in spine is increased do you have such stiffness in spine? When such patients come to our hospital, I advise them blood test like RA factor, CCP, ESR, complete blood count, HLA B27. Hope I have answered your query. Let me know if I can assist you further. </s>
