Muscle strains and pinched nerves are two of the most common causes of pain in the neck, back, or limbs. While they can both cause severe pain, there are distinct differences between the two. A strained muscle is an injury to the muscle fibres, often caused by overuse, overstretching, or lifting something too heavy. This results in localized pain, swelling, and difficulty using that particular muscle. On the other hand, a pinched nerve occurs when surrounding tissues put pressure on or irritate the nerves, interrupting the nerve's ability to send signals properly. This can result in abnormal sensations such as stinging, numbness, or weakness along the affected nerve's pathway. While it can be challenging to distinguish between muscle strain and pinched nerve pain, understanding the underlying cause is crucial for receiving the appropriate treatment.

What You'll Learn
Pinched nerves vs strained muscles
A strained muscle can cause nerve pain, but there are differences between strained muscles and pinched nerves in terms of symptoms, causes, and treatment. Both conditions can cause pain and limit your mobility, but distinguishing between the two is critical to ensure you receive the correct treatment.
Strained Muscles
Strained muscles, or pulled muscles, are common injuries that occur when muscle fibres are torn or damaged due to overuse, overstretching, or lifting something too heavy. This often results in localized pain, swelling, and difficulty using the affected muscle. The pain typically feels like a dull ache and is accompanied by stiffness or tenderness in the area. Unlike nerve pain, strained muscles generally do not cause tingling or numbness. Strained muscles often improve with rest, ice, elevation, and over-the-counter pain medications. Minor strains may heal within a few weeks, while more severe tears may require surgery and physical therapy.
Pinched Nerves
Pinched nerves occur when surrounding tissues or nearby bones put pressure on or irritate nerves. This compression disrupts the nerve's ability to transmit signals, resulting in pain and abnormal sensations such as stinging, numbness, or weakness along the affected nerve's pathway. Pinched nerves commonly occur in the neck, back, or limbs, and the pain may radiate to other areas of the body. For example, a pinched nerve in the lower back may cause pain to radiate down the leg (sciatica). Pinched nerves may not improve as quickly as strained muscles and often require additional interventions such as physical therapy, nerve blocks, or injections. If left untreated, pinched nerves can lead to long-term damage, including muscle weakness or nerve damage.

Strained muscle symptoms
Muscle strains, or pulled muscles, are common but painful injuries. They can often be treated at home, but sometimes they require medical care. The symptoms of a strained muscle include:
- Pain: This is usually localized to the muscle itself and feels more like soreness or a dull ache. It can worsen with certain movements or prolonged positions.
- Swelling and bruising: This is a typical symptom of a strained muscle and can be seen on MRI scans.
- Loss of strength and range of motion: The affected muscle may feel weak, and you may not be able to use it at all. This is more common with acute muscle strains, which happen suddenly and cause immediate symptoms.
- Stiffness and tenderness: The area around the strained muscle may feel stiff and tender.
Muscle strains can be graded based on their severity, from minor (grade I) to severe (grade III). Grade I strains involve only a few broken muscle fibers, while grade III strains tear all the way through the muscle. Acute strains happen suddenly, while chronic strains develop gradually over time. Most muscle strains will heal with time and rest, but severe strains may require surgery and a lengthy rehabilitation process.

Pinched nerve symptoms
A pinched nerve is a compressed peripheral nerve that occurs when surrounding tissues, bones, ligaments, or muscles put pressure on or irritate nerves. This pressure can cause a variety of symptoms, including:
- Pain, which is the most common symptom, can range from a dull ache to a sharp or burning sensation. It may worsen with certain movements or prolonged positions and can radiate to other areas of the body. For example, a pinched nerve in the lower back may cause pain that travels down the leg (sciatica), while one in the neck may cause pain in the shoulders or arms.
- Numbness or a “falling asleep" sensation in the affected area, such as the arm or leg.
- Tingling or a pins-and-needles sensation, which may indicate nerve involvement.
- Muscle weakness or difficulty controlling certain muscles, which can lead to a loss of reflexes in the affected area.
- Limited mobility or range of motion.
These symptoms can vary depending on the specific nerve affected and the severity of the compression. Pinched nerves can occur in different parts of the body but are commonly diagnosed in the back and neck. It is important to seek medical attention for a proper diagnosis and treatment to prevent potential long-term complications, such as chronic pain and muscle atrophy.

Treatment for strained muscles
Muscle strains, or pulled muscles, are common but painful injuries. Most can be treated at home, but some may require medical care or even surgery.
If you suspect you have a strained muscle, you should first assess the severity of the injury. If you heard or felt a "pop" when your muscle tore, or if you can't move the muscle at all, you should seek medical attention right away. Additionally, if your pain, bruising, and swelling are severe, or if your symptoms are not improving or are worsening, it's important to see a healthcare provider.
For minor (grade I) muscle strains, you can expect the injury to heal within a few weeks. These types of strains only pull and break a few muscle fibers and don't tear all the way through. Treatment for minor strains typically involves rest, ice, and over-the-counter pain medications. Gentle stretching can also help improve your range of motion.
Moderate (grade II) muscle strains may take several weeks to months to heal completely. These strains involve more significant damage to the muscle fibers but still don't tear all the way through. In addition to rest, ice, and medication, physical therapy may be recommended to aid in recovery.
Severe (grade III) muscle strains can take four to six months to heal, possibly after surgery. In these cases, the muscle tears completely through, and you may need to immobilize the muscle with a cast for several weeks before beginning rehabilitation. Platelet-rich plasma injections, a newer treatment option, may also be suggested to stimulate tissue repair and speed up healing.
To prevent muscle strains, it's important to properly stretch and warm up before exercising and to ensure your body has adequate flexibility and strength for the activity. Chronic muscle strains can develop gradually when a muscle is overused without sufficient time for repair.

Treatment for pinched nerves
A pinched nerve occurs when surrounding tissues put pressure on or irritate nerves. This pressure interrupts the nerve's ability to send signals, resulting in abnormal sensations such as stinging, numbness, or weakness. It is important to seek medical attention for a proper diagnosis and treatment to minimize the risks of potential long-term complications such as chronic pain and muscle atrophy.
Conservative Therapies
Physical Therapy
Physical therapy, range-of-motion exercises, and strengthening exercises can lead to faster pain relief. Your doctor may prescribe specific exercises to help treat the pinched nerve and improve your condition.
Medication
If your pain is severe, your doctor may prescribe stronger medications. This could include a short course of oral corticosteroids (prednisone), or other anticonvulsant and antidepressant medications that can effectively reduce nerve pain.
Surgery
Surgery is typically a last resort and is not usually considered unless the pain persists after several weeks of medical therapy, there is increasing difficulty in movement, or evidence of spinal cord compression. The exact method of surgery depends on the location of the pinched nerve.
