I have an asthama since long, I got recently vaccinated 1st dose. I have shortness of breath and when I feel it, I used to use inhaler.but I stoped after vaccinated on June 2nd. Can we use inhaler now( after vaccination)when I feel shortness of breath? I always use oximeter and it stands 94 always but not less than. I can smell and no fever, other symptoms except breathing issue..can this would be bcz of covid 19? Can I take RT-PCr or CT , not required? Please can someone advise..also what kind food prefered.
