How Long Does Lower Back Pain Caused Due To Sciatica Nerve Take To Get Cured?

About 4 weeks ago, I experienced the worst pain in my life, due to sciatica nerve, which the ER physician stated it was caused by L5 / S1 degenerative disc. Now, I have no pain in my lower back & R buttock, however I have am still having minor muscle spasm and my last three toes are numb. How long will this last? I have not followed up with a neurosurgeon yet. Perhaps, I am becoming concerned that I'm still have side effects. Any suggestions?
