Lumbar radic : Give it some more time. Try an epidural or selective nerve root block. Seek a surgeon spine for his or her opinion. You will likely not need a surgical intervention.

Weeks to Months: Generally most people can get relief from sciatic pain doing the conservative care within 3-6 weeks. If it persists after that, it can take up to 6 months to heal by itself. You may still be a candidate for epidural steroid injections that may help relieve the pain while your body heals itself.
