<s>[INST] I sneezed and now have a sore chest. Its not a sharp pain, more of a soreness. Between the neck and the above the breast. It hurts to cough and take a deep breathe. But other than that it doesnt hurt to move around. What do you think it could be thats making it sore? [/INST] Hello dear, thanks for your question on Chat Doctor. Pleurisy (inflammation of pleura) can cause soreness in chest after sneezing and coughing. Pneumonia, tuberculosis and pleural effusion etc. are common causes for pleurisy. So better to consult pulmonologist and get done1. Clinical examination of respiratory system. 2. Chest x-ray. If chest x-ray is normal then no need to worry much.  You might be having muscular pain. So better to start painkiller and muscle relaxant. Apply warm water pad on affected site. Don't worry, you will be alright. </s>
