Thanks for posting your query.
L4-L5 spinal canal
stenosis can cause a lower back pain
due to associated disc prolapse
and nerve compression symptoms like numbness and tingling
with shooting pain in the legs.
It is not likely to cause a swelling of the ankles with pain on the knee and the ankle.
The numbness in the hands can be caused by similar spondylottic changes in the cervical spine
. You need to consult an orthopedician for a physical examination and investigations to find out the cause of pain and swelling in the ankle and knee.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
Dr. Praveen Tayal.
