hi, my uncle was in the ICU for 2 days with bp 250/150, they did a MRI and found a small aneurysm - they put him on Lisinopril 40 mg QD, water pill minus hctz, thats all they prescribed, his current bp 136/92 with severe headaches x2 wks, problem w light, feels fine when he wakes up - once he gets to work symptoms reoccur, he works w/ computers what should he do
