@scoop hey scoop glad you are feeling better. I had a similar issue. I’ve been on Brinsupri since 9/5. Did real well until 10/16. That’s the day I got my Covid & Flu vaccination. On 10/18 I took a trip to my local hospital ER, with more sob, body aches, fatigue, and more phlegm, and chest tightness. I had blood work, chest x-ray done and it was determined that my sodium in blood was low 126, (normal is 136-146) its a condition known as Hyponatremia. Now I’ve had this before, But I’m convinced that the Covid or flu vaccine triggered this condition, so is my pcp. Just 2-3 weeks prior my Sodium levels were 134-135, and had been that for the previous 3 months. I’ve been told previously that hyponatremia is common in people with lung disease. Nevertheless the treatment is fluid restriction and salt tablets, and furosemide. I know that there is alot of controversy over the Covid vaccine, in fact Florida is really initiating anti vaccine rhetoric, although it is optional to residents, and to me it seems evidence appears to be growing that maybe this vaccine isn’t as safe & effective as we’ve been told. Anyway it leaves us with an even tougher decision!! Do we get the vaccine or not??? Thank you for listening sorry so long. Also I did file a complaint with the FDA, my pcp says nothing will be done with it, it’s just another data point for them.
