Hi Vickie and Welcome to HealingWell!!
I don't know of any support groups that I could refer you to, however, that is what boards like this exist for-to offer support to others with similar symptoms!
If this is not exactly what you are looking for, you may want to try contacting an American Heart Association Chapter in your local area.
This is a very frustrating disease and I do understand, as I've been having continous angina for weeks now. I'm on a .6 mg. patch of nitro.-I started just a couple of months ago with a .2 mg. patch and have gradually moved up. Somedays, it doesn't feel like that's helping either.
What I've been told is exactly what they've done for me when I was in the ER with these symptoms. You need the nitro. Take it. You need to rest. Lay down. Do you have anything that they've given you to help you relax? You may want to discuss this part with your Dr. I also try taking an acetaminophen or something similar. All this generally does help and some days are just worse than others. Remember to check first with your Dr. and see what he/or she recommends!!
My Best Wishes to You and I hope this has helped,
