Most mid back pain comes from strained muscles or poor posture, and it typically resolves within two weeks with the right combination of movement, stretching, and simple adjustments to your daily habits. The mid back (thoracic spine) is the section between the base of your neck and the bottom of your rib cage, and while it’s less commonly injured than the lower back, it can become a persistent source of discomfort, especially if you sit at a desk for long stretches.
What helps most depends on what’s driving the pain. Here’s how to figure that out and what to do about it.
Why Your Mid Back Hurts
The most common cause is a muscle strain: the muscles and tendons that support the thoracic spine get twisted, pulled, or torn from sudden movements, heavy lifting, or repetitive stress. This includes the muscles between your shoulder blades (rhomboids and middle trapezius), which tend to weaken over time while the muscles in the front of your chest and the tops of your shoulders get progressively tighter. That imbalance pulls your shoulders forward and rounds your upper back, putting constant low-grade stress on the mid back.
Prolonged sitting accelerates this. Hours at a desk cause the chest muscles, upper trapezius, and muscles along the sides of the neck to shorten and tighten, while the muscles responsible for pulling the shoulder blades back and down grow weak. Over weeks and months, this pattern loads the thoracic spine in ways it isn’t designed to handle, producing that familiar ache between the shoulder blades.
Less commonly, mid back pain is referred pain from an internal organ. The gallbladder, kidneys, pancreas, and even the heart can send pain signals to the mid back. The key difference: muscle pain usually changes with movement or position, while referred pain from an organ often doesn’t. If you develop mid back pain with no obvious injury, or it comes with symptoms like nausea, fever, breathing difficulty, or chest tightness, that’s a signal to get evaluated promptly.
Stretches That Relieve Mid Back Tightness
Thoracic mobility exercises are the fastest way to reduce stiffness and ease pain. Two moves are particularly effective.
Thread the Needle
Start on all fours with your hands under your shoulders and knees under your hips. Inhale and lift your right hand toward the ceiling, palm facing away from your body. Exhale and slide your right arm along the floor beneath your left arm until your right shoulder and cheek rest on the ground. From here, lift your left arm toward the ceiling to open your chest further. Take a deep breath, then return to the starting position. Repeat on the other side. Aim for five to eight repetitions per side, moving slowly and breathing into the stretch.
Cat-Cow
From the same all-fours position, exhale and press your hands into the floor while rounding your mid back toward the ceiling. Let your head hang. Inhale and reverse the curve: lift your chin and chest, letting your belly drop toward the floor while your tailbone lifts. Keep the movement smooth and controlled, focusing on feeling each vertebra in your mid back move. Ten slow repetitions is a good starting point.
Both stretches can be done daily. Many people find doing them first thing in the morning and again after a long period of sitting gives the most relief.
Strengthening to Prevent Recurrence
Stretching loosens what’s tight, but preventing the pain from coming back requires strengthening the muscles that have gotten weak. The target is the group between and below the shoulder blades: the rhomboids, middle and lower trapezius, and serratus anterior.
Before any of these exercises, set your shoulder blades in proper alignment. Sit tall, gently draw your shoulder blades back and down (not squeezed together hard, just lightly engaged), and hold for 10 seconds. This “scapula setting” position is the foundation for all of the movements below.
- Lift-off: Lie face down with your arms by your sides. Tighten the muscles between your shoulder blades and lift your arms off the floor while keeping your head on the ground. Hold briefly, then lower. Start with 10 repetitions.
- Wall press-up: Stand facing a wall with your hands at shoulder height. Perform a slow push-up against the wall, focusing on keeping your shoulder blades flat against your rib cage throughout the movement. For more challenge, place a small ball between your hand and the wall to add instability.
- Weight shift on all fours: From the hands-and-knees position, slowly shift your weight forward onto your arms, then back, then side to side. This trains the stabilizer muscles around the shoulder blades to work under load.
These exercises require no equipment and can be done three to four times per week. Progress gradually. If any movement increases your pain, reduce the range of motion or skip it.
Fix Your Desk Setup
If you work at a computer, your workstation is likely a major contributor. Small adjustments make a measurable difference in how much strain your mid back absorbs over the course of a day.
Place your monitor directly in front of you, about an arm’s length away (20 to 40 inches from your face). The top of the screen should sit at or slightly below eye level. If you wear bifocals, lower it an additional 1 to 2 inches. A monitor that’s too low forces you to round your thoracic spine to look down, loading the exact muscles that are already overworked.
Your chair should support the natural curve of your spine. Adjust the seat height so your feet rest flat on the floor and your thighs are parallel to the ground. If the chair doesn’t provide enough back support, a small rolled towel or lumbar cushion placed at the curve of your lower back helps maintain the posture that keeps the mid back in a neutral position. Even a well-set-up desk won’t save you if you sit for hours without moving. Stand, stretch, or walk for a minute or two every 30 to 45 minutes.
Managing Pain in the First Few Days
For a fresh muscle strain, heat tends to work better than ice for mid back pain. A heating pad or warm towel applied for 15 to 20 minutes relaxes the muscles in spasm and increases blood flow to the area. Current clinical guidelines from the American College of Physicians recommend non-drug approaches like heat, manual therapy, and exercise as first-line treatment for back pain, ahead of medication.
If you need additional relief, over-the-counter anti-inflammatory medication can help in the short term. Gentle movement is more effective than bed rest. Staying completely still for days allows the muscles to stiffen further and typically extends recovery time. Light walking, the stretches described above (done gently), and normal daily activities within a comfortable range are the best approach during the first two weeks, which is when most muscle strains resolve.
Massage and physical therapy are both reasonable options if home care isn’t enough. A physical therapist can identify the specific muscle imbalances contributing to your pain and build a targeted exercise program. This is especially worthwhile for pain that keeps coming back.
When Mid Back Pain Signals Something Serious
Most mid back pain is muscular and harmless, but certain patterns warrant immediate attention:
- Pain after trauma such as a car accident or fall, especially if you’re over 60 (compression fractures can result from surprisingly minor force in people with weakened bones)
- Constant, severe pain that doesn’t change with position or rest and gets progressively worse
- Neurological symptoms like numbness, tingling, or weakness in the legs
- Systemic signs including fever, chills, unexplained weight loss, or severe fatigue
- Pain with breathing difficulty, dizziness, or chest tightness, which can indicate a cardiac event or pulmonary embolism
- Pain that follows meals, particularly fatty meals, which may point to gallbladder disease
Pain that hasn’t improved at all after two to four weeks of consistent home care also deserves a professional evaluation. Mid back pain that lingers beyond that window may involve a joint, disc, or postural issue that needs a more targeted approach than stretching and heat alone.
