<s>[INST] Hello. I m a 23 year old female. I just went to the gym two days ago. Yesterday in the middle of a lecture, I had a sudden pain that is very hard to pinpoint in my upper chest area. I ve been able to deduct that it is (sorta) around the right shoulder, collar bone and spreading slightly to the middle of my chest just above my breasts. I had a pain like this last week, which stayed for about three days. It finally went away until yesterday when it came back. It s been almost 24 hours now and the pain has not gotten any better. I ve noticed the pain intensifies if I am either breathing deeply, or if I lean forward on a desk as opposed to leaning back. I m not sure if I should be concerned if these are warning signs of a heart attack or not. If it helps, I was diagnosed with Lupus about a month ago. [/INST] Respected madam, see your age is young, in this age usually heart attack may not come unless very bad food and lifestyle. Here I want to rule out few possibilities that you need to undergo chest x-ray, ECG and auscultation by Cardiologist, if they say you don't have any heart problems, even I believe same. Then we can continue with our protocol. in my opinion, this just overuse muscle injury. In medical terminology we use term known as DOM's, it happens due UN accommodated exercise to muscle. If you have not done proper warm up exercises then you may have this problem. See your physiotherapist and take ultrasound and IT modalities for pain relief for 15 days twice a day if possible. You will be recovered fast. I hope you have satisfied with the answer. Thanks Feel free to ask again. </s>
