I read your message carefully and understood your medical concern.
I came across this information:
- age 62
- lower back pain and stiffness
- diclofenac helps
- comes back after too much vacuuming or something similar
Back pain and stiffness are quite common in people over the 60. The main causes are degenerating processes of spinal vertebral discs and osteoporosis
Dclofenac is an anti-inflammatory drug that helps in reducing the inflammatory process and by this way it relieves the pain. When exposed to special triggers of pain or inflammation the pain re-starts.
Stiffed legs and back in the morning are usual in this situation of spinal or low back joints damage.
My advice is that you must consult a rheumatologist
and run spinal X-ray. Specific tests for rheumatoid arthritis
may be necessary as well as bone densitometry
Apart anti-inflammatories like diclophenac, physiotherapy
can also help after evaluating his current status of vertebral spine.
I hope this was helpful for you.
