I will find out on Monday regarding the sodium issue. A simple serum osmosis test coupled with a standard sodium test can tell one whether they have "pseudohyponatremia", which affects a lot of folks with multiple myeloma. Pseudohyponatremia is basically a false low sodium level. Low sodium in multiple myeloma patients is often just a chemical measurement phenomenom that is due to the presence of more plasma cells in your blood serum that then throws of the standard sodium measurement you get on a basic metabolic panel. You basically need to rejigger your sodium lab measurement results to make up for the increased plasma cells in your blood.
As far as where the proteins are going, who knows? I believe it will likely be either a case of the FLCs forming into larger polymers (tetramers, etc) that are then too big to get through the kidney and/or get electrically repelled by the kidney, or maybe some sort of funky process is going on that causes the FLCs to self destruct (catabolize) faster than usual for their several-hour life.
Or maybe they are hiding elsewhere and are going to spend the weekend in one of my ear lobes
No idea if this is anything I should be concerned about, or if the docs will even want to chase this down. Will find out soon enough.
Thanks for asking.
