Go to review a day later with good response, pain 5/10, continue with tramadol. the blockade was made 2 more times each week, with a gradual decrease in intensity of pain 2/10 of burning type that is exacerbated when carrying out daily activities. Complex regional pain syndrome (CRPS) was defined in 1993 by the International Association for the Study of Pain (IASP) as one:"Variety of painful conditions of regional localization, after a lesion, presenting a distal predominance of abnormal symptoms, exceeding in magnitude and duration the expected clinical course of the initial incident, frequently causing significant motor deterioration, with a variable progression over time. " The diagnosis It is done by applying Budapest criteria by the IASP. The treatment are several therapeutic approaches among which we find medical and pharmacological treatment, psychological treatment, occupational therapy, rehabilitation treatment and more recently the treatment with spinal electrical stimulation. Although the therapeutic approach of CRPS requires a multidisciplinary approach, the most important thing is that the treatment be early, individual, progressive and painless.
