Lignocaine Infusions: What They Are & How Physiotherapy Supports Recovery

Lignocaine, also known as lidocaine, is a local anaesthetic and antiarrhythmic drug that works by blocking signaling from nerves to the brain. While it is commonly used in dentistry and minor surgical procedures, intravenous (IV) lignocaine infusions are increasingly being used to manage chronic pain conditions that have not responded well to other treatments.

Lignocaine infusions are particularly beneficial for people with neuropathic pain, fibromyalgia, complex regional pain syndrome (CRPS), post-surgical pain, and persistent musculoskeletal pain. These conditions often involve heightened nerve sensitivity, and lignocaine can help by calming overactive nociceptive (danger) pathways.

At PhysioPM in Townsville, we often assist patients who undergo lignocaine infusions as part of their pain management plan. While these infusions can provide temporary relief, physiotherapy is essential for helping you move better, regain strength, and manage pain in the long term.

What to Expect from a Lignocaine Infusion

If your doctor has recommended a lignocaine infusion, here’s what you can expect:

1️⃣ The Procedure – Lignocaine is administered intravenously (IV) over 30 minutes to a few hours, depending on your specific pain condition and treatment plan. The goal is to reduce nerve overactivity, leading to less pain and improved function.

2️⃣ During the Infusion – You will be monitored closely for any side effects. Some people experience drowsiness, light-headedness, or tingling sensations, but these are usually mild and temporary.

3️⃣ After the Infusion – Many patients experience a reduction in pain and hypersensitivity, allowing them to move more freely. Effects can last from days to weeks, depending on the individual.

4️⃣ Possible Side Effects – Temporary symptoms such as fatigue, nausea, dizziness, or mild numbness are common but typically resolve quickly.

How Physiotherapy Can Help After a Lignocaine Infusion

While lignocaine infusions can help reduce pain, they do not treat the underlying causes of movement-related discomfort. This is where physiotherapy is essential. At PhysioPM in Townsville, we create personalised rehabilitation programs to help you take advantage of your pain relief window and restore function.

🔹 Safe, Progressive Movement – Reduced pain after an infusion may encourage increased activity, but doing too much too soon can cause flare-ups. A physiotherapist helps guide gradual movement progressions.

🔹 Strength & Conditioning – Chronic pain often leads to muscle weakness and deconditioning. A targeted strengthening program ensures safe, sustainable improvements in mobility.

🔹 Sensory & Nerve Desensitisation Techniques – For conditions like CRPS or neuropathic pain, physiotherapy can include graded exposure and sensory retraining to help your nervous system become less reactive.

🔹 Education on Pain Management – Understanding how to modify activities, manage flare-ups, and maintain movement without triggering pain is crucial for long-term recovery.
