Welcome to HealthcareMagic forum.
Guillain Barre Syndrome or simply GB syndrome is a condition that affects nervous system leading to progressive weakness of skeletal muscles. Sometimes sensory disturbances may be accompanied by muscle weakness
), however pure sensory disturbances are unlike GB syndrome.
Definitive diagnosis can be established by EMG studies, examination of cerebrospinal fluid
and detailed neurological examination.
Chronic Inflammatory Demyelinating Polyneuropathy
(CIDP) needs to be ruled out when symptoms are predominantly sensory as seen in your case. A brief course of steroid and other immune suppressant might help you.
I encourage you to consult a neurologist
if you haven't met one yet for a detailed neurological examination. Review of your earlier tests and if needed re evaluation may be needed.
Hope this answers your query.
All the best!!
