<s>[INST] I am 6 1/2 months pregnant. Woke up this morning having chest pain. I didnt pay mind to it and continued with my day. Afternoon I took two Tylenol thinking the pain would go away and it hasnt. The pain is my dead center chest, in between my breast. Feeling like I cant breath. Like my chest is Caving in and someone punched me there a few times. What is it????? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more likely. But better to rule out cardiac chest pain first. So get done blood pressure monitoring and ECG. If both these are normal then no need to worry about heart diseases. Apply warm water pad on affected areas. Avoid movements causing pain. Take painkiller and muscle relaxant Chat Doctor. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
