hi,
thank you for providing the brief history of your husband.
As he has already undergone the
spinal fusion at L4-L5 levels , and recurrent surgeries of the back it appears that the lumbar disc are not in good shape.
Also, the MRI indicates the
nerve root injury and needs a thorough examination.
Also, post surgery if he is not relieved of pain than the surgery couldn't help him due to
muscle weakness which keeps on leading to
nerve root compression.
Also, to Control the symptoms of numbrness, tingling and pain you can arrange a meeting with a physical therapist and undergo Therapeutic ultrasound therapy and TENS therapy for pain relief. Also, exercises will help but before undergoing any exercises the surgical neurological assessment is advised.
As the pain is chronic in nature instant recovery cannot be expected as well.Kindly keep the patience and meet up the surgeon to discuss further.
In my clinical practice , such cases with spinal surgeries respond well to
physical therapy. And slow , steady recovery is achieved.
Regards
Jay Indravadan Patel
