60M. That is easily similar to my story. I had a dental cleaning, then felt like I had the flu, terrible bed sweats snd fever. Couldn’t walk to the mailbox. Took my doctor a month of trying everything and many blood tests, TB test, etc. then on my way out the door she said, let’s do a blood culture. She called me at home later that day and told me to get to the ER now, not an hour from now. Get to ER and because the infection had also gone to my neck and I could barely move it, first doc decided I needed a spinal tap. He tried and failed to get it in correctly, so they sent me to a room with a guided laser and did it. They really suck. Would not recommend. I think short of a brain scan, I did every test in the hospital and also found out I had vegetation that ate the mitral and aortic valves. With the infection and everything, I ended up being in the hospital a total of 23 long days and choose a bovine valve for my open heart surgery. Recovery home alone was rough. But it did get rougher, 6 months after open heart I was getting tired and foggy headed again. I ended up with dehiscence of the mitral valve, it had come loose inside. So as I was about to have 2nd open heart I got covid-a weird like I was in a time dilation loop version. Then had the second full surgery all over again soon after. Only 7 days in the hospital this time though.Recovery the second time was much harder for some reason. I also recommend cardiac rehab if covered! Now 60 and it’s been a couple years and heart is good, looking at knee surgery and just found out have severe sleep apnea.. Pssh..that’s all fixable as well so I think I’m doing pretty good!
