Ivermectin & repercussions from long covid

An earnest question for those more experienced than
myself. I think (almost sure) that I caught covid mid January when I visited my aged mother in law in
a rehab facility that experienced an outbreak. She
supposedly tested positive but to me showed no obvious symptoms other than being 94 & having her
share of maladies. The staff there had a makeshift
covid ward. I had to don a n95 mask, face shield &
gown to enter.
She did not seem any sicker but her roommate sure did... obese, hacking & coughing & no room divider & of course no negative pressure (the AC was linked to all the nearby rooms)
I started feeling it come on 2 days later & it was
not pleasant but not so bad I needed hospitalization. Though it cost the wife and I to have to miss seeing her alive before she spiraled
down and having to miss her funeral, we did recover
largely after 3 weeks.
Since then about 4 to 5 months I have had a lingering cough and bronchial inflammtion. I have started seeing an osteopath PA & we are exploring
what might be happening.
My sincere question to those more knowledgable than I, is over me tin effective skiing after contact & would it be advisable & safe?
If I had access to it then I certainly would have
used it then but I did not. I have access to it now
(12mg pills) so I am asking if it would do me any good. I have not been vaccinated, am a 68 yr old in
Decent health, no prescription meds and just quit all smoking as its too hard on the cough.
Thanks in advance for any advise you may have!
