[|Human|] Hi. I have a heavy crushing feeling in my chest back and ribs. Im bringing up quite alot of mucus sometimes like a brown colour sometimes it looks like it has blood in it. And i have awful pain in my left side and under armpit when takin a deep breath.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. By your history and description, possibility of lower respiratory tract infection (LETI) is more. Chest discomfort with pain and brownish mucus expectoration are common symptoms of LETI - pneumonia. Chest pain on breathing is characteristic feature of pleurisy (inflammation of pleura) and pneumonia is the most common cause for this. So better to get done chest x-ray for the diagnosis of pneumonia. You may need antibiotics, bucolic and expectorant Chat Doctor.  Hope I have solved your query. Wish you good health. Thanks.
