Everything you need to know about trigger point injections


Muscle pain is a common complaint among athletes and non-athletes alike. It is important that you know how to recognize it and what to do when it occurs.

If you have experienced muscle pain, you may be wondering why it has occurred, whether it’s serious, and what you can do to treat it. The following information will help you understand the symptoms of muscle pain and the best ways to treat them.

Chronic muscle pain can have a significant impact on a person’s ability to function and their quality of life. Trigger point injections may offer immediate benefits to people who have chronic muscle pain.

trigger point injections

Trigger point injections are injections of local anesthetic, steroids, and/or botulinum toxin that are used to help relieve muscle pain. The injections are given directly into the painful area and can be performed by a physician or by trained health care professionals.

Uses of trigger point injections?

Trigger point injections are used to treat pain caused by conditions affecting the musculoskeletal and nervous systems, such as the ones listed below.

Myofascial pain syndrome

Myofascial pain syndrome is characterized by persistent muscle pain, tenderness, and limited range of motion. It can also cause headaches and tingling sensations in the skin. It usually affects more than one muscle group, leading to widespread pain.

Myofascial pain syndrome is caused by trigger points (also called knots), which are small areas of tightness in the muscles. Trigger points are often caused by an injury or trauma, but they can also be present without any apparent cause.

Trigger point injections are an effective treatment for myofascial pain syndrome. These injections contain anesthetics and steroids that help to release the tightened muscle fibers and decrease inflammation around them so that they can relax again.

According to researchers, trigger point injections can reduce localized muscle pain by relaxing the affected muscles. Trigger points are small areas of hardened and tender muscle that develop when a muscle is injured or overused and become painful when pressed.

Trigger point injections interrupt the nerve signaling pathways that cause referred pain, which is pain felt at a distance from its source in the body. This can be helpful for many people who suffer from chronic back pain.


Fibromyalgia is a chronic condition that causes pain and stiffness throughout the body. In addition to these physical symptoms, people with fibromyalgia also experience fatigue, irritable bowel syndrome, headaches, depression, and anxiety.

The exact cause of fibromyalgia is unknown. It can be difficult to diagnose because symptoms vary from person to person, and there are no specific tests for it. However, it’s often misdiagnosed as chronic fatigue syndrome or rheumatoid arthritis.

While there’s no cure for fibromyalgia, treatment options can help manage symptoms and improve quality of life. These may include medications such as antidepressants and anti-seizure drugs; physical therapy to help reduce pain; or cognitive behavioral therapy to improve sleep habits or manage stress levels.


Trigger points are small knots of tense muscle in the body that can cause pain in other areas of the body. In this case, they can refer to pain from trigger points in the upper back and neck to the head.

Trigger points are often caused by stress or injury, but they aren’t always easy to diagnose. A doctor may be able to feel them when they press on a patient’s muscles, but other times they’re only visible through an X-ray or MRI scan after injection with a contrast agent.

Myofascial trigger points are areas of muscle tension that are painful to the touch. These points can be found in individuals with episodic or chronic tension-type headaches. In a 2016 study, researchers examined the relationship between myofascial trigger points and pressure pain sensitivity in people with these types of headaches.

Individuals with more myofascial trigger points reported higher levels of pressure pain sensitivity than those with fewer points.

Do they work?

Trigger point injections may offer immediate pain relief and improved range of motion for people with chronic muscle pain.

Trigger point injections are a treatment option that involves injecting a numbing medicine, called an anesthetic, into the trigger point. Trigger points are areas of tightness in the muscle that can cause pain, limited movement, and other symptoms.

Trigger points occur when a muscle becomes overused and tightens up, or when it is injured. They can be caused by a fall or injury that strains your back muscles or neck. Trigger points can also develop after you sit in one position for too long or do repetitive movements such as typing or mowing the lawn.

The needle used to inject the anesthetic into the trigger point is very small—usually between 0.5 and 2 millimeters long—and is inserted just under the skin on top of the affected area. The medicine works by temporarily blocking nerve impulses from reaching your brain so that you don’t feel any pain while it’s being injected or afterward.

Researchers behind a small 2019 study investigated the effects of these injections in people with abdominal muscle pain. The participants reported significant reductions in pain 2 years after the initial injection, with five requiring additional injections and another experiencing no response to the treatment.

Although trigger point injections may offer significant benefits, various researchers have found that this therapy can be ineffective. While some patients report immediate relief from their pain, others report no change or even worsening of symptoms.

This may be due to the fact that trigger point injections are not always effective for all patients. Some experts believe that injecting a single trigger point at a time will not address the underlying cause of muscle pain. Instead, they recommend focusing on treating multiple trigger points simultaneously in order to get better results.


Trigger points are hyperactive areas within a muscle that cause pain when pressed. These points can occur anywhere in the body but are most often found in the back, neck, shoulders, buttocks, and legs. Trigger points can also be found in the jaw muscles and tendons around joints such as those of the fingers, hands, and elbows.

Trigger point injections may be used to treat chronic pain conditions if other treatments have not worked well enough or have caused side effects that are too severe for you to tolerate them.

Trigger point injections are a treatment option for certain types of back pain. An injection may be used to inject a local anesthetic, corticosteroid, or botulinum toxin A into the trigger point. The purpose of these injections is to reduce inflammation and pain in the muscles by reducing pressure on nerve endings.

The injection may provide immediate pain relief for some people, while others may have no response to the treatment. A doctor can provide more detailed information about the risks and benefits of this treatment.
