Hello, I'm sorry that you were going through this. I have written many comments on this blog in the past, I'm not sure if there is a way to go back and read them. I have been dealing with long covid for a year this past April. I have been hospitalized six times. Bizarre symptoms from a to z primarily heart issues, feeling like I was going to pass out etc. I started doing a lot of online research in the UK, Israel, and of coarse the well trusted Mayo. Six months ago after a lot of research, I decided to start taking probiotics, also mango leaves (I bought them on amazon in a tea bag form) because of many things I had read stated, to fight any auto immune disease you have to start with your gut immunity. At the time I could not think of being on a tennis court, could not make plans to do any activity as I had no idea how I would be feeling. I am making a very long story short, there were many things I could no longer do, including just taking a walk. I am very athletic and that is a big part of my life. I decided to give it a try. After taking probiotics and mango leaves (tea form) I started feeling better. I stayed feeling well for 5 months, back on the court, traveling etc. A month ago I felt off again, rapid heart beat, exhausted, the nightmare all over again! Sure enough, ended back in ER. Because I had been so busy, I forgot about the probiotics (Florastor) and the mango tea leaves, subconsciously I believe I thought I was better and did not think about either. Right away when I started thinking about what I did or did not do that had changed I remembered I was not taking either. I started faithfully drinking 3 cups a day of the tea, and 2 probiotics daily. I am feeling so much better, not sluggish, on the court again, feeling like myself, (my old self before long covid) NO I do not work for either company, I happen to be retired. I'm not trying to give anybody false hope. But if this can help just one person I would be so happy as I know what it is like to suffer with this. It changes your complete life. I made up my mind 6 months ago that this was not going to owe me and I wasn't going to accept it. Yes I know it's easy to say but I had to transform my mind into knowing that I was going to fight this. I didn't talk about it everyday, as I stopped talking about it and started fighting it. I hope this helps anybody! Take care of yourselves, fight this anyway that you can!
