Chest & Breathing Problems

Hello sir, Good evening Just I went for PFT My report details are FVC             76% FEV1.          78% FEF 25-75. 102% PEF.             99% FIVC.           88% Is my report normal Pls suggest further examination required

My father(age 62) was diagnosed with covid -19 with CT severity score 21/25 and was admitted in hospital with oxygen support for around 25 days. The medications in hospital included Steroids , anti-coagulants, anti-fibrotics and other medicines. Now, he has been at home for last 1 month and doing physiotherapy and other breathing exercises ( and bed rest for majority of the time ). His spo2 levels while resting is 97-98., But when he walks for 5-10 minutes or does little physical exercise , his saturation falls to 90-91 . (He also still has little dry cough) When will spo2 level fluctuations improve ?

Last year in the same time I got cough for about more than 2 months, x ray chest was done and doctor told that it is allergic bronchitis and given medication but no relief. At that time I took homeo medicine from drug standardisation unit of Ayush and got recovered. This time even after 1 month after my COVID recovery cough is not cured. It is getting wiresened in the night times. Kindly sugggest me medication or any diagnosis tests required to confirm the problem

My sister-in-law got covid positive 2months back and recovered completely a month back. Now she got cough so did a CT scan. Wanted to check if this report is normal.

Just curious to know.. have seen a young lady at vaccination center wearing 3 masks...is it really required ?? And also does it reduces oxygen supply ?? And does it anyway affect the vaccination and immune process ??..

I tested positive. I was in home quarantine and now am fully recovered. I am totally normal. But sometimes i can see some black particles in my phlegm. Not fully black some black particles. Why does this happen. Is it anything serious?

I was detected with covid19 on 13th may, now i have recovered from covid. I am having sore throat and mild pain in my thighs. Is there anything to worry about ?

I had covid on April 15th. I went to ENT specialists thrice last week( May 25-29). I did an antibody test and it had IGM 5.1 and IGG 1.28. I am scared of reinfection as I have a scratchy throat since last week. Can I get reinfected?

My father had covid in last month and cured in home isolation,now d dimer report has 675 now what to do,what is the medication for this.plz some one help me.

Good evening Sir/madam , How many days after testing covid-negative can vaccine be taken ?. Please advice, thanks.
