Sprains and Strains
Reviewed by board-certified emergency physicians. Walk in or call (713) 660-0001 anytime.
A sprain is a stretched or torn ligament (the tissue that connects bone to bone), while a strain is a stretched or torn muscle or tendon. A fracture is a broken bone. Because a severe sprain and a fracture can cause the same pain, swelling, and difficulty moving, an X-ray is often the only reliable way to tell them apart. Bellaire ER has on-site X-ray to rule out a fracture and treat the injury in a single 24/7 visit.
Symptoms
- Pain: Sharp or aching pain at the joint or muscle that worsens with movement or weight-bearing.
- Swelling: Rapid swelling around the injured joint or muscle, often within minutes to hours.
- Bruising: Discoloration that develops over hours to days as small blood vessels are damaged.
- Limited motion: Difficulty moving the joint or using the muscle through its normal range.
- Popping sensation: A pop or snap felt or heard at the moment of injury, common with a torn ligament.
- Instability: A feeling that the joint gives way, buckles, or cannot bear weight (more typical of a sprain).
- Muscle spasm or weakness: Cramping, tightness, or loss of strength in the affected muscle (more typical of a strain).
When It's an Emergency
Visit the ER for sprains and strains if:
Your symptoms are severe, sudden, or getting worse. Don't wait — walk in to Bellaire ER or call (713) 660-0001.
Come straight to Bellaire ER — open 24/7 — if you have signs that suggest a broken bone or serious injury (call 911 if you cannot travel safely): a visibly deformed, crooked, or bent limb; bone pushing against or through the skin; or a snap or crack heard at the moment of injury followed by immediate, severe swelling.
Seek emergency care if you cannot bear any weight on the leg or foot, cannot take four steps, or cannot move or use the injured joint at all. These can be signs of a fracture rather than a simple sprain.
Get immediate care for numbness, tingling, or a cold, pale, or bluish limb, finger, or toe below the injury. This can mean nerves or blood flow are affected and needs urgent evaluation.
Also come in for severe or rapidly worsening pain and swelling, a wound over the injury, or any injury that does not clearly improve with rest, ice, and elevation over a few days.
When It's Not an Emergency
Most mild sprains and strains can be cared for at home with the RICE method: Rest the injury, apply Ice for 15 to 20 minutes several times a day, use Compression with an elastic bandage, and Elevate the area above heart level to reduce swelling. Over-the-counter pain relievers such as acetaminophen or ibuprofen can help if you have no reason to avoid them.
If you can bear weight and move the joint, the pain is mild to moderate, and there is no deformity or numbness, a telemedicine visit or a call to your primary care doctor is a reasonable first step. Seek in-person care if pain, swelling, or bruising is not improving after two to three days, or if you are unsure whether the bone is broken.
What Happens at Bellaire ER
When you arrive at Bellaire ER with a sprain or strain, you are seen quickly by a board-certified emergency physician who examines the injured area, checks your range of motion, circulation, and sensation, and asks how the injury happened.
If a fracture is possible, we take an X-ray on site to rule out a broken bone. Our full imaging suite also includes CT and ultrasound when a deeper injury is suspected. Because everything is on site, you get answers during the same visit.
Once the injury is diagnosed, your physician treats it — this may include a splint, brace, wrap, crutches, pain control, and clear home-care instructions. We diagnose and treat in a single visit, and most patients do not need a hospital transfer. Before you leave, your physician explains your results and gives you a follow-up plan.
Prevention
Warm up before exercise and stretch afterward, and increase the intensity of activity gradually rather than all at once. Building strength and flexibility in the muscles around your joints helps them absorb stress.
Wear supportive, well-fitting footwear for your activity, and use proper technique when lifting or playing sports. Keep floors and walkways clear of clutter and use good lighting to reduce trips and falls, which are a common cause of ankle and wrist sprains.
Frequently Asked Questions
How can I tell a sprain from a fracture?
You often cannot tell them apart by feel alone, because a severe sprain and a broken bone both cause pain, swelling, bruising, and trouble moving. Warning signs that point more toward a fracture include a visible deformity, bone tenderness directly over the bone, inability to bear weight or take four steps, or a snap heard at the time of injury. The only reliable way to confirm is an X-ray, which we perform on site at Bellaire ER.
What is the difference between a sprain and a strain?
A sprain is an injury to a ligament, the tough tissue that connects one bone to another at a joint; ankles, knees, and wrists are common sites. A strain is an injury to a muscle or a tendon, the tissue that attaches muscle to bone; the lower back and hamstrings are common sites. Sprains more often cause joint swelling and instability, while strains more often cause muscle spasm and weakness. Both are treated with rest and, in some cases, a splint or brace.
How do I treat a sprain or strain at home?
For mild injuries, use the RICE method: Rest the area, apply Ice for 15 to 20 minutes several times a day, wrap it with Compression using an elastic bandage, and Elevate it above heart level to limit swelling. Over-the-counter pain relievers such as acetaminophen or ibuprofen can ease discomfort if you have no reason to avoid them. If pain and swelling are not improving after two to three days, have the injury checked.
Do I need an X-ray for a sprained ankle?
Not every sprain needs an X-ray, but you should have one if you cannot bear weight, have bone tenderness at the ankle, notice a deformity, or the injury is not improving. An X-ray rules out a fracture that can look identical to a bad sprain. Bellaire ER has on-site X-ray available 24/7, so you can get an answer during the same visit.
How long does a sprain or strain take to heal?
Mild sprains and strains often improve within one to three weeks with rest and home care, while moderate injuries can take several weeks and severe tears may take months or need specialist care. Returning to activity too soon raises the risk of re-injury. If pain, swelling, or instability lasts beyond a few weeks, follow up with a physician for further evaluation.

People also ask
When should I go to the ER for sprains and strains?
Go to the ER for a sprain or strain if you cannot bear weight or take four steps, the limb looks deformed, there is bone tenderness or numbness, or the pain and swelling are severe. Mild injuries with preserved movement can often start with home care, telemedicine, or your primary doctor.
