<s>[INST] just had awful pain in between breast that shot up neck.  I took a baby asperian and laid down. layin down didn't help. as suddenly as it came, the pain left.  I have a cold at present.  It was a bit scary (the pain).  Took blood pressure and it's 121/72 [/INST] Thanks for your question on Health Care Magic I can understand your concern. Possibility of aspirin induced gastritis and acid reflux is more but better to rule out cardiac chest pain first. So get done ecg and 2d echo first. If all these these are normal then no need to worry for major heart diseases. Aspirin is known to cause gastritis and hyperacidity. So this will cause reflux of acid in the esophagus and this will give central chest and neck pain. So take antacid like proton pump inhibitor at present. Avoid aspirin tablet. Drink cold water. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
