Hello, and welcome to 'Ask A Doctor'

Thanks for posting your query.

I have gone through your query. I need more details. Do you have fever, cold or cough? Any other illness or co-morbiditis? Are you taking any medicines for any disease?

Breathlessness and erratic sleep can be due to stress or anxiety also.
Meanwhile, you can take:
Cap. Becadexamin once daily for 30 days
Tab. Calcimax forte Plus once daily for 30 days.
For sleep disturbance, you can use melatonin skin patch 30 mins before going to bed. Use it for a week or 10 days and then you can slowly alternate and use it only when required.

To relieve stress, deep breathing exercises for 20 minutes twice daily and regular walking not brisk for 30 minutes daily helps control BP and anxiety.

I hope this helps. Please feel free to discuss further if any.
Regards,
