Moreover my body which is trembling with horripilation, with a bristling of hairs; slips, falls down and is burning, feeling scorched all over.

Madhvacarya has no commentary so we present Baladeva Vidyabhusana's.

Vepathuh means trembling, romaharsah means horripilation, the Gandiva bow slipping from his hand shows impatience and paridahyate which is burning of the skin is a burning of the heart also.

Here Arjuna is vividly illustrating how the shock and horror of the upcoming war is starting to affect him. His physical body is being attacked by weakness of limbs, parchness of throat, horripilation and hair standing on end. Even his famous Gandiva bow slipping from his hand.
