I am a Non-smoker (never) and have never had a problem with breathing. My oxygen level has dropped significantly since COVID shots. This has been pointed out by 3 doctors so I am now being referred to a pulmonologist. I have an appointment in July and will follow up with results. COVID SHOTS have also caused me to have so many UTI’s (never had one before) that my urologist has had to put me on a low dose antibiotic.
