Im suppose to have a lumbar fusion on my lower back soon and recently been waking up with numbness in both arms, is this related?
Yes and no
The problems you are having in your lumbar spine are not causing the symptoms in your arms, but new numbess in the arms may be indicative of the same degenerative process which occurs in the lower, or lumbar spine, only occuring in the neck, or cervical spine.
If the symptoms persist or worsen, you should let your surgeon know prior to any planned surgery.
