Brief Answer:
The doctor should have judged it safe to let you go home, so very likely you are going to be fine but it is safer to plan in case a worsening happens
Detailed Answer:
Hello and welcome to "Ask a Doctor" service,

I carefully read your query and also checked the uploaded report.

It seems your doctor is trying to differentiate between pulmonary vascular disease (disease of the blood vessels that send the oxygenated blood from the lungs to the heart) and interstitial lung disease which consists of problems with the lung areas between the arteries.
There are several possible conditions that may cause each of these two categories of lung problems.

Generally, interstitial lung diseases and some pulmonary vascular diseases tend to be more subtle and gradual. A few pulmonary vascular diseases may pose the risk for quick worsening and an emergency.

Until now it is not clear which is the most likely cause of your symptoms (vascular or interstitial), thus it is important to go with your symptoms.

If your shortness of breath at rest is worse or shortness of breath with exercise worseness (you are not able to do activities you are currently doing) then you should see a doctor as soon as possible.

On the other hand, I believe the doctor that set the order for CT scan and allowed you to go home should have already judged that you are safe to stay home.
Meanwhile, while you wait to have the test, you should have a plan B in case you worsen, so you should already have targeted a hospital you can use (is easily accessible and offers the service you need).

Also, make sure you are around people so in case you get a sudden worsening someone can assist you.

To conclude:

- the physical examination in the doctor's office should have given the doctor enough clues to determine the emergency of your condition so very likely you are safe to stay at home as the doctor should have judged it safe when he allowed you to go home.

- on the other hand, it is good to be prepared in case a worsening happens. You will need to have targeted a medical center that you can easily and quickly access and that may assist you. Make sure you have people around that may assist you in case of need.

- very likely you will be fine but if any worsening of your shortness of breath (at rest or reduced exercise that you can do) or any new symptoms, you will need to see your doctor as soon as possible.

I hope this answers your query.
I remain at your disposal in case further medical assistance is needed.

Regards,

Dr. Antoneta Zotaj,
General and Family Physician
