Dude I was thinking the same fucking thing like dude go to the er man why are u even playing around with shortness of breath... Only thing I can think is if he nicked a corn and got alil oil into his blood, or maybe ur getting covid either way that needs to seriously be checked out u could have water around ur heart man..... There is a couple possiblites here. Get it checked out get the proper bloods and scans done. I would also check ur BP brother and idk what ur family history is like but if u have high bp u might wanna get on a low dose BP med and if u have heart disease in ur family ur calcium score is in the high normal range and ur cholesterol isnt great normal shit with antibiotics but u might wanna get a scan to see how it arteries are something as simple as eziembe, obv discuss this with ur physician and maybe even a cardiologist. It's just something to check out being so many bbers are passing and things taking place getting regular check ups and scans are good catching something earily is much better then catching it to late. Happy belated Thanksgiving brother hope ya feel better also if ur on a cruise I'd lower ur dose to atleast 150-200mg max if ur on a cruise give urself a proper break
