I am 46 and have been experiencing a dull pain in my left lung off and on for the past 3 weeks..Monday Morning I went to the er..and they checked for a blood clot--which was negative..they did a lung x-ray but did not give me the answer to that they did blood work and then perscribed Diaxon....is this for a lung infection?..before I could ask the doctor he was gone..
Thanks for your question on Chat Doctor. I can understand your concern. No, it is not antibiotic, so it is not for lung infection. It is painkiller. So you are not having any lung infection. Your pain is mostly musculoskeletal pain. So along with this Chat Doctor.  1. Avoid movements causing pain. 2. Avoid heavyweight lifting and strenuous exercise.3. Apply warm water pad on affected areas of chest.Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
