Cherrys symptoms and conditions

Been on lisinopril for about a year for high bp. Seems to help. Don't have a cough and don't seem to be feeling weak or sluggish. Do have a burning sensation on the tip of my tongue and a couple of really sore bumps have come and gone on the last few weeks. Also, I am now developing may little red cherry like blood blisters on my body just about everywhere. I've had the dermatologist look at them and he called them some kind of skin cherry and nothing to worry about. I know they are somewhat genetic and my father has a few but I am getting hundreds of them and it has been within the last 6 months. I was told this medicine dialated the artery going into the kidneys to relieve pressure. Wonder if it is dialating capalaries in my skin causing these cherrys? Anybody else got 'em?
