Chronic pain is a type of persistent pain that lasts for an extended period of time, typically more than three months, or beyond the normal healing time for an injury or illness.

Unlike acute pain, which serves as a warning signal for tissue damage or injury, chronic pain may persist even after the initial cause of the pain has healed.

Chronic pain can originate from various sources, such as injuries, surgeries, medical conditions, or unknown causes. It can affect different parts of the body, including muscles, bones, nerves, and organs.

Chronic pain is a multifactorial disease with different causes that contribute to its onset and perpetuation. Biological, psychological and social factors play an important role in the progression of the disease.

Sever chronic pain is a massive medical and social problem. This fact led to the evolution of pain clinics over the years, where innovative minimal invasive technologies and novel drug delivery systems are induced to the field of curing chronic pain conditions.

New modalities of pain management have evolved the last years, along with many classic conventional approaches. Most of these procedures are well tolerated and safe and can be performed under local anesthesia on a day care basis.

A multipurpose treatment approach is commonly needed in order to treat chronic pain syndromes and provide function and quality of life.
