### output:

Thanks for your question on Chat Doctor. I can understand your concern. If connective disease is ruled out and since your CT chest are normal as told by you, no need to worry about lung infection. Possibility of bronchitis is more in your case. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test) with lung volumes and DCO. PFT is needed for the diagnosis of bronchitis. It will also tell you about severity of the disease and treatment of bronchitis is based on severity only. Now since rashes are not your problem and cough I'd only issue now it should felt with. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
