My mother has arterial dissection of the abdominal aorta. her medications in Losartan 100 mg, 1xd; hydralazin 25 mg, 3xd; metoprolol, 25mg, 2xd; and hydrochlorothiazide 12.5 1xd. When she takes the hydralazine she gets burning sensations in her limbs and sometimes up the side of her throat. The doctor has dismissed this as nothing. Can you tell me if this is something we should be concerned about? It does make her want to skip the medication totally.
