Hi and thanks for the query, a greater characterization and understanding of the issue of burning is necessary to be understood. Conditions like inflammations with poorly controlled lupus, viral infections, electrolyte abnormalities and peripheral nerve disease could cause the burning sensation A clinical evaluation is mandatory to orient further testing. Consulting an orthopedic surgeon of a reference hospital could guide you on how to obtain what you want. However, a proper clinical reevaluation by a rheumtologist to confirm and elucidate evolution of lupus is important. Poorly controlled lupus could also contribute to such symptoms. I suggest you consult your orthopedic surgeon and rheumatologist for evaluation and advice. The neurologist might be important to exclude the nervous component of these burning sensations. Thanks and best regards, Luchuo, MD.
