Additional treatment options

Neuropathic pain management

Pharmacological intervention using medications that modulate nerve function, such as certain antidepressants or anticonvulsants, to address associated sensory abnormalities.

medication

Sensory re-education therapy

Targeted exercises designed to improve sensory perception and proprioception through graded sensory stimulation techniques and balance training.
