Today, i woke up, and after i showered and ate, i felt pain around my heart. i didn’t think it was anything so i just went along and walked around the mall. then after i ate there, the pain went away, but now im home and it hurts getting up after i lie down, and it hurts if i breathe in alot. do i have angina? is there anything i can do to stop the pain? because i just woke up with the pain. my uncle who is a nurse said it was just muscle pain, which i think it is, because it hurts when i get up. so can anyone tell me what i have and what i can do to stop it?
