@marinab, I'm happy that he has been able to make his decision. I imagine that this has to be a relief to have taken that step. However, I am so sorry that he now has to wait. It's probably not much comfort, but he is not alone with having a delayed surgery due to a covid surge.
I was looking at some old notes today, and saw that I had gained 7 1/2 inches on my waist before my 1st paracentesis. I don't know how much fluid was drained. But I remember the discomfort with the fluid. Is your husband going to be able to get the fluid drained when he needs it during this delay?
