Additional treatments depend on the condition that is causing the sciatica.</p><p>If these measures do not help, your provider may recommend <a test="test" href="./007485.htm">injections</a> of certain medicines to reduce swelling around the nerve. Other medicines may be prescribed to help reduce the stabbing pains due to nerve irritation.</p><p>Nerve pain may be very difficult to treat.
