Some background.
I'm a former paramedic / rescue and I have had 4 heart attacks plus 5 vessel bypass surgery. I also can get chest pain on excertion. I absolutly hate going to the hospital as a patient. I see this issue from both sides.
First no two patients are the same regarding the amount of pain or ability to function. I have witnessed far to many patients saying nothing was wrong and as I'm watching the monitor thier heart stops.
My best advice to you is this simple rule.
If you experience any type of chest pain STOP what you are doing and try to sit down. Then take one nitro tablet under your tounge. If the pain gets worse call an ambulance and get help.
If the pain starts to subside after the 1st nitro but does not completly go away after 5 minutes take a second nitro.
They used to say three nitro 5 minutes apart and if still having pain call an ambulance. But in my experience if you need the 3rd nitro you should be checked out. So if after 2 and still pain I'd get help.
Again if at any time after taking the nitro the pain gets worse get help and don't wait.
I have learned to live with my heart issues and I know when to get help. For 80% of my chest pain I can get relief by simply stopping what I am doing and resting no need for the nitro. When I do need it I rarely get to 2 tablets.
My best advice is if you get chest pain and your not sure what to do please be smart and get help.
You can live a good life with heart issues you just have to be a little careful.
If you do end up needing stents don't worry to much about the procedure. The only discomfort is the local numbing shots in the area where they are going to insert the catheter. I have never felt the wires etc as they are inserted. You can get an overall body warmth when they inject the dye but that is about it.
I wish you well and hope things get better for you.
