What is low back strain?
Low back strain is an injury to your lower back muscles or tendons. Tendons are strong tissues that connect muscles to bones. The lower back supports most of your body weight and helps you move, twist, and bend.

- You lift heavy objects with your back instead of your legs.
- You do not warm up before you exercise.
- You sit or stand for long periods of time.
- You are overweight.
What are the signs and symptoms of low back strain?
- Low back pain or muscle spasms
- Stiffness or limited movement

How is low back strain diagnosed?
An x-ray, CT scan, or MRI may be done to check for damage to your spine, muscles, or tendons. You may be given contrast liquid to help the tissues in your lower back show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
How is low back strain treated?

Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
- Muscle relaxers help decrease pain and muscle spasms.
- Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation.
