<s>[INST] What would cause chest pain, feels kinda like an infection of some sort, but have no other symptoms, pretty much a slight dry cough, slight mucus, but no color. Just a raw feeling when breathing. I did have a sinus infection about 3 weeks ago, got better, now the chest issues have gone on for around 2 weeks. [/INST] Hi thanks for asking question here...Noted slight chest pain with cough...Do you have fever ???Here I want first to do your auscultation and physical examination to rule out creps or rhonchi.You might have bronchitis like condition.Chest x ray useful for it....If need proper antibiotic given....Chest x ray also rule out consolidation like condition suggestive pneumonia...If need sputum examination and culture useful....If you have chronic gastritis like condition then chest pain and dry cough can occur...Take care... </s>
