Re Injuring

I had to delete my original account but a few years back they said they guess I herniated a disk or 2. Lost all feeling in my leg, excruciating pain. Recovered to about 99%.
I havent had a sore back in sooooo long. And now, my lower back sending sharp pains to my buttcheek and leg. I'm scared I've re injured myself.
Do you think if I rest and listen to my body I'll heal itself or think it's just gonna go full blown again. I'm so scared to go through that damn pain again. I can't do it again..
