Treatment of chronic pain

Pain therapy or analgesic therapy, is a branch of medicine that aims to treat chronic and often refractory pain by controlling painful stimuli in order to improve the quality of life of treated patients.

Pain symptomatology involves two types of treatments, the pharmacological one through the use of drugs administered according to the nature and intensity of the painful stimulus; the nonpharmacological one through invasive interventional practices such as spinal cord neuromostimulation implants , radiofrequency , intrathecal pumps for drug delivery into the subarachnoid space, and Pens. All practices that aim to neuromodulate the pain stimulus generated by the peripheral nervous system.
