My current appointments and place of work

We have long known that chronic pain has genetic components, but we did not know which types of brain and nerve cells are influenced by these genetic differences in humans. This study aimed to answer that question by combining a very large chronic pain genetic dataset with advanced single cell analyses of human nervous system tissues. The knowledge can open the door to the development of more effective treatments.

Surgery can lead to chronic pain, likely due to persistent nerve damage, inflammation, and alteration in the processing of pain signals in the spinal cord and brain.

New research highlights the benefits of combining biological and psychosocial measures when identifying biomarkers for pain. This supports the biopsychosocial model and urges a holistic approach to pain management. However, practical challenges like the cost and time involved in comprehensive testing remain, necessitating further investigation to evaluate the integrated approach's feasibility and effectiveness in improving patient outcomes.

Injections for low back pain may work even if patients know that they are receiving a placebo. What does it mean for pain management?

Pain neuroscience education aims to improve the patient's understanding of pain, and can lead to reduced pain and better function.

Disc degeneration is considered a cause of low back pain, but is common among individuals without pain. Does it mean that it is unimportant?

The placebo effect relies on patient’s expectation that a treatment will help. It is a welcome way to enhance pain relief.

The classification of pain into acute (<3 months duration) and chronic (>3 months) lacks scientific support and clinical usefulness.

Pain at the upper neck and headache can stem from the C1-2 joint. Steroid injection or surgery can be effective

Sensitization of neural pathways is a crucial determinant of chronic pain, and has treatment consequences. How to explain this to patients?

A new research pathway is proposed to translate discoveries of pharmacological targets into effective treatments of pain.

Tenderness evoked by pressure is typically interpreted as a sign of injury causing pain. However, it is of very limited diagnostic value.

Pain from multiple body sites is frequently highly disabling. 1+1+1 is more than 3. Why, and what can we do?

We need to understand better chronic pain at individual level. The study of metabolites (metabolomics) is a promising perspective.

We need to translate the complexity and heterogeneity of chronic pain into meaningful diagnoses.

Muscles can be a source of pain Everyone, at a certain point of their life, has felt pain in their muscles, and some have muscle pain...

Pain sensitivity has a complex nature. Its understanding will be crucial to better treat patients with pain.
