[|Human|] How concerned should I be? About a year ago I had a PE in my lung, which did clear. In the past few weeks I have been short of breath, have a cough, pain/discomfort in my chest. I also took my pulse oxygen stats which are 91%. It was much worse a couple days ago, but its still uncomfortable.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should rule out recurrence of pulmonary embolism (PE) in your case. Your symptoms like shortness of breath, chest pain, coughing etc. are seen in PE. Your saturation is also low (91%). Normal saturation of oxygen should be above 95%. Decrease in saturation also seen in PE. And it is very common for PE to recur after 1 year. So you should definitely get done chest x-ray and CT pulmonary angiography to rule out recurrence of PE. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
