So sorry to hear this, my mom has had some close calls with kidney function (creatnine levels,etc.) due to her diabetes and history of high blood pressure, which both she is on meds. for.
Though she has had stents, and now pacemaker too, the body over years of both diseases undiagnosed or under medicated has put the wear and tear, the meds now, just sort of slow things down or keep them under control.
I'm sending out positive energies to both of you, for strength and healing.
Take care now,
Roe
