Localized infiltration of cortisone aims to reduce inflammation and thus pain. It is a treatment method for various pathologies that have not responded to treatment or that have persisted for several months. Whether it is for plantar fasciitis, neuroma or a gout attack, this technique is recognized as a treatment with the goal of definitive healing. Finally, infiltration is often used in combination with another technique such as strapping/taping, orthotics or conservative treatments.
