See a doctor if back spasms are severe, don't improve within a few days, or are accompanied by leg numbness, weakness, or bladder problems. Seek care if spasms follow an injury.

Warning Signs That Need Immediate Attention

Frequently Asked Questions

What causes back spasms?

Back spasms are commonly caused by muscle strain from heavy lifting, sudden movements, or poor posture. Dehydration, stress, and underlying spinal conditions like herniated discs can also trigger spasms.

How do I stop a back spasm immediately?

Apply ice for the first 48 hours to reduce inflammation, then switch to heat. Gentle stretching, over-the-counter anti-inflammatories, and resting in a comfortable position help. Avoid complete bed rest beyond a day or two.

How long do back spasms last?
