<s>[INST] My husband, age 48 went to the doctor today and has had pain off & on for 6months but the last week the pain has gotten more intense (pain on upper right side under rib cage going to the back). They did blood work (CBC & cmp) those both came back normal, had moderate blood in urine, had ultrasound of and & had a ct/Abd without contrast and they both dame back normal. Not sure what is going on, any suggestions? [/INST] as age increases backache and knee pain will be due to degenerative changes.as the workup shows eberything is normal,advise him to take analgesics . </s>
