Never take your back for granted - always have it checked out. I should know - I have three prolapsed disks (L1-L2, L4-L5 and L5-S1) - all from lifting, moving and digging clay out the front yard when we were building.
Have it checked out, because it will settle and continually re occur until you have a treatment plan. Mine is physio and pilates. Surgery is last option these days.
Take some pain killers and go and buy a heat bag - Best $30 I've ever spent !
