How Often Can You Get Trigger Point Injections?
Updated: 05/28/2026
Pain can build up and make it hard to move, sleep, or get through the day. Tight muscles often cause this pain, and rest does not always help. Trigger point injections can ease the pain by relaxing the muscle. Many people ask how often you can get trigger point injections because they want relief without problems.
In many medical plans, trigger point injections are usually not given more often than every 2 months. A repeat injection is usually only suggested if the last one helped reduce pain and improve movement or daily function.

How Often Can You Safely Get Trigger Point Injections?
There is no single schedule that works for everyone. The frequency of trigger point injections depends on several factors such as your diagnosis, the severity of pain, and how your body responds to treatment.
In many clinical practices and insurance policies:
- Repeat therapeutic trigger point injections are often spaced about 6 to 8 weeks apart
- Some policies require at least 2 months between injections
- A repeat injection may be recommended only if the previous one reduced pain by about 50 percent and the relief lasted several weeks
Let’s see how often you can get trigger point injections based on different conditions:
Chronic Conditions
Some people deal with pain for many years. Conditions like fibromyalgia and myofascial pain create muscle knots that stay tight. These knots do not go away on their own. In this case, trigger point injections for chronic pain can help reduce pain over time. Doctors often give these injections every 6 to 8 weeks for people with long-term pain. This schedule gives your muscles time to relax and heal.
Acute Injuries
When pain comes from a new injury, the body may respond quickly to treatment. If you strain a muscle or hurt your back, the best doctor might give trigger point injections once a week for a short time. This helps calm the muscle and reduce pain early. Most people move to fewer injections after a few weeks.
Post-Surgical Pain
Some people feel pain after surgery even when the wound heals. Muscle tightness or scar tissue can make movement hard and painful. Trigger point injections can help relax these muscles and make recovery easier. Doctors usually space these injections six weeks apart.
The number of injections depends on how much pain you feel and how your body heals. It is important to know how often you can get trigger point injections in Scottsdale after surgery so you do not delay recovery or cause more pain.
Here’s a summary table:
Situation | Typical timing | Notes |
Chronic myofascial pain | Often 6–8 weeks or longer | Depends on relief duration |
Acute strain | Short-term individualized schedule (maybe once a week) | Not a fixed rule |
Post-surgical pain | Based on recovery and response | Coverage may vary |
Insurance-covered therapeutic injections | Often at least 2 months apart | Depends on payer policy |
What Affects How Often You Can Get Trigger Point Injections?
Several factors influence the trigger point injections frequency:
- People with severe muscle pain or large trigger points may require more than one treatment session to fully relax the muscle.
- If the injection provides relief for several weeks or months, doctors usually wait until the pain returns before repeating the treatment.
- Chronic conditions such as myofascial pain syndrome may need ongoing treatment. Acute muscle strains often improve faster and may need fewer injections.
- Insurance companies and Medicare often limit how frequently trigger point injections can be billed. Many policies require documentation that the previous injection provided significant pain relief and lasted long enough to justify another treatment.
Signs It’s Time for Another Trigger Point Injection
Pain may return four to six weeks after the injection. This usually means the shot worked, but the effect has worn off. If the last injection gave good relief and the tight muscles come back, your doctor might plan another one. These signs help your doctor decide how often you can get trigger point injections without overdoing it. If the pain comes back too quickly, your treatment plan may need to change.
Signs you may need another injection:
- Pain comes back after 4 to 6 weeks
- You felt more than 50% pain relief from the last injection
- Muscle tightness returns in the same spot
- Pain makes it hard to do daily tasks again
- Relief from the injection lasted only a few days
How Long Do Trigger Point Injections Last?
Pain relief from trigger point injections can vary from person to person. Many patients feel improvement within a few hours or days after the injection. The relief may last:
- A few weeks
- One to two months
- Sometimes longer if the muscle heals and physical therapy strengthens the area
Why Regular Trigger Point Injections Work Better
Regular trigger point injections work better because:
- They lower the pain for a longer time
- They help prevent new muscle knots
- They give your muscles time to relax and heal
- They reduce the need for pain pills
- They support better movement and faster recovery
Are There Risks to Getting Trigger Point Injections Too Often?
Trigger point injections are generally considered safe when performed by trained medical professionals. However, repeating injections too often can increase the chance of side effects.
Possible side effects include:
- Temporary soreness at the injection site
- Minor bleeding or bruising
- Infection at the injection site
- Tissue irritation if injections are repeated too frequently
- Steroid related effects if corticosteroids are used repeatedly
Most side effects are mild and short lived. Your doctor will monitor your response and adjust treatment to keep the procedure safe.
Let’s Recap
Trigger point injections can provide relief from painful muscle knots and myofascial pain. The exact schedule for repeat injections depends on your condition, your response to treatment, and insurance rules.
In many cases:
- Relief lasts several weeks or longer
- Repeat injections may be spaced around 6 to 8 weeks or according to payer guidelines
- Doctors usually repeat treatment only if the previous injection provided meaningful pain relief and improved function
