<s>[INST] Hi Doc I am getting a sharp pain in the middle of my chest, just a bit towards the left side , between both breasts. It lasts for about 2 minutes and then goes away. It is extremely painful to breathe when I get the pain. It been happening about once/twice a day for the past week.Please advise Thank you [/INST] Firstly you go through your self breast examination and try to figure out if you have any lump in your breast or your breast is painful or not. If its normal then you go ahead and get your cardiac workup done </s>
