Trigger Point Injections
Trigger point injection (TPI) may be an option for treating pain in some patients. TPI is a procedure used to treat painful areas of muscle that contain trigger points, or knots of muscle that form when muscles do not relax. Many times, such knots can be felt under the skin. Trigger points may irritate the nerves around them and cause referred pain, or pain that is felt in another part of the body.
In the TPI procedure, a health care professional inserts a small needle into the patient’s trigger point. The injection contains a local anesthetic or saline, and may include a corticosteroid. With the injection, the trigger point is made inactive and the pain is alleviated. Often, a brief course of treatment will result in sustained relief. Injections are given in a doctor’s office and usually take just a few minutes. Several sites may be injected in one visit.

Trigger point injections essentially target areas of irritation within the muscles surrounding particularly arthritic joints or irritated nerves that are then triggering the irritated muscles.
The goal of trigger point injections is to minimize pain, muscle irritability, and spasm, and to reestablish normal posture and range of motion.
The initial treatment is individualized and based upon the severity of the symptoms each patient experiences and, of course, the extent of their individual disability because of those symptoms.
The treatment goal for any patient requiring trigger point injections is not only to inject the trigger point itself but also to diagnose or come to a conclusion about the underlying cause of these issues—whether it be osteoarthritis, poor posture from long workdays, or other inflammatory autoimmune conditions that may be the underlying cause of this issue.
At Seaside Rheumatology, any patient evaluated for pain and trigger point injections will also be evaluated for these underlying causes.
Frequently Asked Questions About Trigger Point Injections
How do I know if my muscle pain may benefit from trigger point injections?
Trigger point injections may be recommended for persistent muscle knots or areas of tightness and tenderness that cause pain at the source or discomfort that radiates to nearby areas. These sensitive knots, known as trigger points, may develop after muscle overuse, injury, repetitive movements, or ongoing muscle tension. If stretching, rest, physical therapy, or other conservative treatments have not provided enough relief, your provider may evaluate whether trigger point injections could be an appropriate part of your treatment plan.
How do trigger point injections help relieve muscle knots, pain, and tightness?
During treatment, a small needle is carefully inserted into the affected muscle area where the trigger point is causing pain and tension. The injection may include a local anesthetic or other medication selected based on the patient’s specific symptoms and treatment needs. Needle placement itself can also help relax the contracted muscle fibers. By targeting the specific source of discomfort, treatment may reduce muscle tension, improve movement, and interrupt patterns of pain that make everyday activities uncomfortable.
What types of muscle pain and conditions are commonly treated with trigger point injections?
Trigger point injections can be utilized to address painful muscle knots and myofascial pain in regions like the neck, shoulders, upper or lower back, and various other muscle groups. Trigger points can occasionally lead to referred pain, which means that discomfort is experienced in a different area from where the tense muscle is situated. At Seaside Rheumatology and Wellness Center, patients are carefully evaluated to determine whether symptoms are related to trigger points or to another musculoskeletal or rheumatologic condition that requires a different treatment approach.
Do trigger point injections hurt, and what can I expect during the procedure?
Most trigger point injection procedures are brief and performed in the office. Your provider identifies the painful muscle area and carefully inserts a small needle into the trigger point. You may notice mild pressure or brief discomfort as the injection is administered. Temporary soreness afterward is possible and generally improves within a short period. At Seaside Rheumatology and Wellness Center, treatment is tailored to the location and severity of your symptoms, with attention to both accurate placement and patient comfort.
How fast do trigger point injections take effect, and what is the duration of pain relief they provide?
Some patients notice reduced muscle tightness or discomfort shortly after treatment, while others experience improvement over the following days. How long trigger point injection relief lasts varies depending on the cause of the muscle pain, the number of trigger points, activity level, and other individual factors. Relief may last from days to weeks or longer. Combining injections with stretching, physical therapy, improved posture, or other recommended treatments may help address factors contributing to recurring muscle tension.
How many trigger point injections will I need for chronic muscle pain?
The number of injections needed varies from patient to patient. Some people benefit from a single treatment, while persistent or recurring trigger points may require additional sessions. Your provider will consider the location and severity of your pain, how long symptoms have been present, and how you respond to initial treatment. Trigger point injections are generally used as part of an individualized pain management strategy rather than automatically scheduling every patient for a predetermined series of treatments.
What should I do after trigger point injections, and when can I resume normal activities?
Many patients can return to most routine activities shortly after trigger point injections, although your provider may recommend temporarily avoiding strenuous exercise involving the treated muscles. Mild soreness, tenderness, or bruising can occur at the injection site. Gentle movement or stretching may be recommended depending on your condition. At Seaside Rheumatology and Wellness Center in Encinitas, California, patients receive individualized aftercare recommendations designed to support recovery, maintain mobility, and help them get the most benefit from treatment.
