Could Eating Salty Sunflower Seeds Be Causing Chest Pain And Shortness Of Breath?

Hi. I am a 34 years old male, and I've never had any health issue except for my kidney stone. I live alone in the State and since been in the State I never had salty(mild) sunflower seeds. I went back to my country and in the way back, I brought some salty sunflower seeds with me. I eat the sunflower seed like once a day. Now, I feel I have a difficulty breathing and I can feel that I have a chest pain, and I have never never had chest pain or short in breathing. Do you think the sunflower seeds were the cause of my short breathing and chest congestion?
