Brief Answer:
Cardiac cause unlikely

Detailed Answer:
Hello and welcome,

I appreciate your concern,

Please go through the below-mentioned differentials, which I've summarized after going through the clinical details:

Antibodies to SARS CO V can be advised if you are worried about SARS to allay your fears. The clinical picture in association with blood counts and chest x ray findings should be correlated before concluding a diagnosis.

If an infectious cause is suspected with a high TLC count then antibiotics like Clarithromycin or Co-Amoxiclav (eg. Augmentin) should be advised. If the chest is wheezy then nebulization with bronchodilators should also be done. A short course of corticosteroids would also help in this scenario.

If a cardiac cause was already ruled out and the altitude sickness also subsided then I would advise a Pulmonology consultation. Pulmonary function tests can be done to look for any obstructive or restrictive lung disease pattern.

If no GERD symptoms are present then hiatal hernia is unlikely though it can accurately be diagnosed on an upper GI endoscopy if suspected and no other cause is found. Though I would keep it pretty low on my differential list.

Let me know if you have any query,

Wishing you the best of health

Thanks

Hello again

Yes asthma is a possibility.
Asthma diagnosis would require clinical examination and pulmonary function tests. Treatment can then be advised accordingly. The dyspnoea refers to difficulty in breathing and would interfere with sleep. The cause of the dyspnoea needs to be determined as the two aren't related.
