<s>[INST] A month ago I was having trouble breathing with pains in my chest. I had a series of test done and all came back normal. I also have a instal hernia and had the endoscopy done. Well, about a week ago, I was still having chest discomfort and my doctor prescribed medium twice a day. Now, I have noticed these small, sore bumps inside my right chest muscle. Im feeling better except now Im concerned about these bumps that hurt to the touch. What could they be? [/INST] Thanks for your question completely understand your question chest pain can be due to a variety of reasons whether it be cardiac, lung related or just gastritis, peptic ulcer.in your case as small swellings are present a FNAC of the swelling should be done, and accordingly it can lead to a diagnosis histologically .it seems like these swellings and chest discomfort over ribs is due to Costco Chat Doctor.  </s>
