Pinched Nerve in the Back: Symptoms, Causes, and Warning Signs

The back can seize up so suddenly that a person freezes mid-step, afraid to breathe deeply. The sensation varies: dull aching heaviness, a shooting pain radiating into the leg or under the shoulder blade, a band of numbness on the skin. Next — calmly and factually: what may be compressed, how it manifests, and which signs mean you should not delay.

What "a pinched nerve in the back" means

"Pinched nerve" is not a diagnosis but a lay description of a sensation. In medicine, a similar condition is called radiculopathy: a neuralgic syndrome caused by compression of spinal nerve roots. The pain can be felt in different places: in the neck, back, limbs, and the area of internal organs. After compression, inflammation sets in: the immune system reacts to contact between disc tissue and the nerve sheath, resulting in irritation of fibers, impaired microcirculation, and edema.

Back pain is one of the most common medical problems: 8 out of 10 people experience it during their lifetime. Acute pain comes on suddenly and usually lasts from several days to several weeks; it is called chronic if it persists for more than three months.

Symptoms of a pinched nerve in the back

The picture consists of pain and neurological details that the person notices themselves:

• shooting, stabbing, less often burning pain in the area served by the affected root;
• reduced sensation in the same area — the skin feels as if it is "not one's own," touch is perceived differently;
• weakness in the muscles innervated by the compressed root;
• increased pain when coughing, sneezing, moving, and lifting heavy objects, especially in an upright position.

Sometimes pain during sleep is accompanied by redness and swelling of the skin and increased sweating.

Pinching under the shoulder blade and between the shoulder blades

Radiculopathy is classified by the type of affected roots: cervical, thoracic, and lumbosacral, and the type determines diagnosis and approach. Pain originating from the upper back, between the shoulder blades, is a reason to see a doctor, although low back pain is more common. A common cause of back pain is injury such as a muscle strain.

Why a nerve gets pinched: possible causes

The main compressive cause of radiculopathy is a hernia and other diseases of the intervertebral discs, including osteochondrosis; spinal fracture and spondylolysis are in the same category. There are many causes of back pain. Most often it is an injury such as a muscle strain, sometimes a displaced disc or sciatica, which is precisely a pinched nerve, as well as ankylosing spondylitis. Very rarely the cause is serious: a bone fracture, tumor, or infection.

How a doctor determines the cause of pain

Radiculopathy is recognized by characteristic signs: pain with root irritation plus at least one neurological symptom indicating root dysfunction. Instrumental methods include radiography and magnetic resonance imaging. There are neurophysiological studies — electromyography and nerve conduction testing; together they are more informative, but they can confirm radiculopathy rather than rule it out. The doctor also asks about what is not visible on imaging: whether there was an injury, whether the person is losing weight without reason, whether there is pain at night.

Warning signs and when to see a doctor

But back pain has symptoms that require emergency care.

A pinched nerve by itself is not a reason to call an ambulance; 103/112 — if, against the background of back pain, weakness, tingling, or numbness appeared in both legs; sensation was lost around the genitals and anus; bladder or bowel function changed — difficulty urinating or the person cannot hold urine and stool; sensations in the genitals changed, it is impossible to achieve or maintain an erection, there is no orgasm; there is chest pain; the pain began after a serious accident.

Without delay, you need to see a doctor if you feel fever, chills, or general malaise, as well as with sharp pain that began suddenly or is rapidly increasing.

A routine visit is needed if the pain does not go away after several weeks of treatment, interferes with everyday activities, if the person has lost weight without effort, a lump or swelling has appeared on the back or its shape has changed, the pain does not ease after rest or worsens at night, becomes worse when sneezing, coughing, or going to the toilet, and also if it originates from the upper back, between the shoulder blades. If the pain is severe or does not improve within three days, or appeared after an injury, seek care without waiting three weeks.
