Hello, I recently got very upset and angry. I started shaking, crying and started to have these pain in my lower back, around the kidney area on both sides and it felt like something was punching me continuously. Later that evening my throat also felt like it was swelling up inside or feeling like I was being strangled, with pain in my chest. I was scared to go to sleep, because of this feeling. I am 54 years old female. Could you please tell me what was happening with my body or what it was?
