Hello doctor... I was having sudden burning sensation in lateral border of left side of tongue from 5 months..but it only happens during sleep nd I wake up due to this sudden electric shock like sensation in the tongue. It doesn't happen in any other time but only happens during sleep in afternoon nd at night. Also I have noticed recurring ulcers on the tongue at the same side which r not healing even after taking bcomplex nd applying corticosteroid. They recur after every 1-2weeks. But now from 15 days or so the burning sensation is occurring in mouth also nd when there's no ulcer then also. Plz advise me what to do nd whom to consult. Iwill be highly grateful.
