calf muscle twitching (2023)

Why it's not a good idea to ignore it

A twitching calf muscle doesn't seem like a big deal, and if it's just a passing nuisance that lasts a few days and then goes away, it may be. But it can also be aWarning sign of something bigger, especially if moving on. So today we're going to explain a little bit about the calf and why it's not a good idea to ignore calf muscle twitches.

What is the calf muscle?

If there's one muscle you're probably familiar with, it's the calf muscle. When you reach around and grab your calf and flex it, the muscle you actually feel just beneath the surface is called theGastrocnemius Musclein medical terminology.

The top of the muscle attaches behind the knee and the bottom is connected to the Achilles tendon, which extends to the heel. If you're a runner, or even just a regular exerciser, chances are you spend time stretching your calf muscle—first because it feels really good, and second because it helps protect the muscle from damage. And who hasn't woken up in the middle of the night with the dreaded calf cramp?

What Causes Calf Muscle Twitches?

The calf muscle, like every muscle, has oneInnervation. That meansIt has a nerve that supplies the muscle and tells it what to do. The nerve branch for the calf musclestarts at the top of the lower spine.

If the nerve is injured or just irritated, it can cause the calf muscle to twitch involuntarily (fasciculateis the medical terminology), a reflex response when the muscle does not receive instructions from the nerve on what to do.

So what can injure the nerves in the calf muscle?Severalnerves can.

For example, the S1 (Sacrum Level 1) nerve in the lower back becomes the tibial nerve in the leg, which then innervates the calf muscle.If there is a...Bulging or herniated discB. at the S1 level, this can put pressure on the nerve and this nerve irritation can manifest itself as a muscle twitch in the calf.Likewise, an injured shin nerve can also present as a twitching calf muscle.

Let's take a look at an actual twitching calf muscle

Calf muscle twitching can be so subtle that you might not even notice it, or it can be dramatic and even create some pressure in the calf, or it can be somewhere in between.Watch the very short video of Dr. Centeno, in which a patient's calf muscle twitches dramaticallyas well as an ultrasound image, as the twitching occurs versus a muscle that does not twitch.

To stop the twitching caused by nerve irritation, treat the nerve

Themost common cause of twitching calf muscles in S1 nerve irritation in the back. Typically, this nerve irritation occurs because of a disc problem or inflammation from arthritis that puts pressure on the S1 nerve.So to stop the twitching caused by an irritated S1 nerve, the nerve must be treated. In interventional orthopedicsWe can treat this problem epidurally with a platelet lysate.

Growth factors from the patient's blood platelets are injected around the irritated or injured nerve under precise image guidance.In addition, a larger herniated disc can be treated with an injection of specially cultured stem cells, provided the degeneration of the disc has not progressed too far.

While it may be okay to shake off a calf twitch that happens once or twice and doesn't come back, it's never a good idea to ignore a persistent calf twitch.It's a big red warning flag that the nerves aren't working as they should.And as always, it's best to treat a problem when the warning signs appear, rather than waiting and trying to treat once a problem has grown into something bigger and more difficult.

Annular crack

To understand annular tears, let's first look at the anatomy of the spine. The lumbar spine consists of 5 bony building blocks, the vertebral bodies. The intervertebral discs lie between the vertebral bodies. Each disc consists of an outer fibrous ring, the annulus fibrosis, surrounding the inner gelatinous center called the nucleus. The intervertebral disc absorbs the forces of everyday life. The ring has multiple layers of collagen that provide important support. The annulus is similar to the sidewall of a tire which provides important stability to the tire. Trauma or degeneration can damage and/or weaken the outer annular fibers.

Degenerative Scoliosis

Degenerative scoliosis, also known as adult-onset scoliosis, is a disease that causes the spine to bend sideways. The bend can be slight, moderate, or severe, with lateral bending to the right or left. The term degenerative means general wear and tear and is common with age. Degenerative scoliosis is the curvature of the spine that occurs as a result of degeneration of the intervertebral discs, small joints, and building blocks. The curve of degenerative scoliosis is often in the lower back, forming a C-shape. There is a convex side and a concave side. The convex side is the open side where it curves outward.

Failed Back Surgery Syndrom

Failed Back Surgery Syndrome, also known as Failed Back, is a clinical condition in which patients who have undergone lower back surgery continue to experience pain and dysfunction. In other words, the surgery intended to relieve pain and improve function FAILED. That's right, the operation failed. You had the surgery, struggled with the postoperative pain, diligently participated in physical therapy, and yet the pain and limitations are still there. Unfortunately, this often happens. It is estimated that 20-40% of patients who undergo lower back surgery will develop failed back surgery syndrome. Pain is the most common symptom of failed back surgery syndrome…

disc prolapse

A herniated disc is particularly difficult because there aren't as many treatment options as there are for herniated discs in other areas of the spine. To understand herniated discs, however, we must first understand the anatomy and function of the thoracic spine. In the case of a herniated disc, the annulus fibrosus develops small tears throughout the annulus. An annulus is a bundle of concentric fibers. So when the fibers are damaged and cut, the pressure built up in the core pushes the now weakened annulus outward, causing a bulge or rupture. The disc begins to weaken due to slight degeneration/tearing of the annular fibers...

Pinched nerves in the back

We talk a lot about leg pain resulting from a pinched or irritated nerve in the lower back. And indeed, our doctors are traditionally taught this in medical school - a pinched nerve in the lumbar spine typically shows up as a symptom in the leg. However, what if you have butt pain but no leg pain or other symptoms? Does that mean it can't be a pinched nerve? Not so fast. It turns out that a pinched lower back nerve doesn't always have to be accompanied by leg symptoms. Let's start by taking a look at how the back is constructed.

Herniated disc, herniated disc, overgrowth of the facet joint, and thickening of the ligaments can result in compression or irritation of the nerve root and cause symptoms of sciatic compression. Some causes of sciatic compression may be related to the following conditions: degenerative disc disease, spinal stenosis, disc damage or injury, spondylolisthesis, piriformis syndrome, osteoarthritis. Symptoms of sciatica include pain in the lower back, buttocks, and down the leg, numbness and weakness in the lower back, buttocks, leg, and/or feet, increase in pain with movement, "tingling" sensation in the legs, toes, or feet. , loss of bowel control and incontinence. Sciatica can be treated...

Torn slices

The intervertebral discs are shock absorbers that live between the vertebrae at each level (1). They have a tough outer ring portion and a soft inner gel portion (nucleus pulposis). The outer shell can become damaged, which can sometimes be seen on MRI and sometimes requires additional testing for identification. These tears are referred to as a herniated disc, herniated disc, annular tear, and on MRI the “high intensity zone” or HIZ. They can cause pain, usually from ingrown nerves. There are disc tears that can be seen on MRI (HIZ) and these can be either asymptomatic (i.e. not painful) or…

Why is my calf muscle twitching? ›

"Fasciculations occur when innervation from the peripheral nervous system to the muscle is not working correctly and a muscle is triggered involuntarily, causing it to twitch," says Dr. Ondo.

Does ALS cause leg twitching? ›

In ALS, motor nerve cells (neurons) waste away or die, and can no longer send messages to muscles. This eventually leads to muscle weakening, twitching, and an inability to move the arms, legs, and body.
