Hi Sam,
It is a pretty scary thing, but you will get through it! After experiencing what I thought was acid reflux while bow-hunting elk in Colorado with my three sons and a couple of friends in September, It was discovered I had heart disease I was unaware of. Back home I left the hospital after 4 days with 5 stints placed in 4 arteries. I was very, very lucky. I had no heart attack thus no heart damage. The blockages are delt with but I have to take meds and live better for the rest of my life! I have was bowhunting Kentucky whitetails 2 weeks later! This will just be a set back for you! You will come out of it feeling much better! Just follow doctors orders!
Good luck! Prayers headed your way!!
Harry
