Dear Mr.vjr Many a times the nerve gets under pressure due to some local causes which in majority of cases is inflammatory in nature. The continous pressure on nerve leads to pain in the supply area or numbness to the area supplied by it. Entrapment of the nerve or other related problems of the nerve itself can lead to such symptoms. The prescribed investigations can pin point the cause. Amongst herbal medicines we use punarnava and guggul combinations as the exert anti inflammaory and muscle tonic effect along with ashwagandha which is known nervine tonic and has property for nervous repair.
