Lifestyle issues
According to research, people who spend more time sitting tend to experience worsening symptoms of sciatica. The condition can be improved by gentle exercises. Experts believe that moving the sciatic nerve can help reduce nerve sensitivity, and as a result, improve symptoms. Your doctor may recommend stretching and exercising as a treatment method.
Spinal mass or tumour
A cancerous mass on the spine can exert pressure on your sciatic nerve. A malignant peripheral nerve sheath tumour is a rare type of tumour that may result in the worsening of sciatica.
