What I have come to understand on this site and for myself..... is that the "vest(s)" are not always helpful nor a one size fits all for various reasons such as causing other problems due to how it is pumping somewhat at the stomach, above the waist and below the neck. on the entire area, systems, and parts within us and not just the lungs.
I would imagine your doctors would like to know what is happening. Hope the 'more bleeding' stops.
