I Damaged My Back On Saturday When Bending Forward Into

I damaged my back on Saturday when bending forward into the pantry. I heard a crunch and then knew that I'd done something to my lower back, right hand side. Now it is Thursday and I have had a lot of trouble getting out of bed, turning right, spasms, and "grab me" pain. Advice please. I have used ice initially, then heat. Also taking Voltaren 25, but not often. Have used some essential oils but not a lot of relief from that.
