I was having pains whenever I took in a breath so I took 1 NitroQuick pill and it didn't help, so I took 1 more and it still didn't help, but I started feeling really
weird, having chills and getting sleepy. I still had the chest pain and called my cardiologist. They advised they didn't think the chest pain was heart-related since I just had a heart catheterization and it was normal.They thought it could be an anxiety attack.
