<s>[INST] So ive had a common cold for the past 5 days and yesterday and the night before i had this sore tight aching feeling in my left outter chest kind of under my armpit but a bit up more then today it felt fine with a little burning feeling but in the same place could possibly tell me what i have I think it is cosoconditis is how i think you spell it [/INST] Hi, Costochondritis can cause similar symptoms. As of now you can take analgesics like Paracetamol or Ibuprofen. If symptoms persist better to consult a physician and get evaluated. Nothing much to worry as it will settle by itself. Hope I have answered your query. Let me know if I can assist you further. </s>
