No med changes, stress, or illness. Lead dr on his transplant team retired so we've been working with his local nephrologist who can't explain the drop/fluctuations and just says the biopsy sample looked good, but dodged my direct question as to whether he'd seen this dynamic before and how those scenarios played out, which leads me to suspect that the answer is "not great". I understand that doctors are loathe to talk actual facts and numbers, but it's put us in a position that we don't know what to do. There's a job opportunity that would nearly double my salary, but we'd have to move and then I have no earned vacation saved, no seniority, etc. If the bottom may drop out on him I'm better to stay where I am, if he's stable we're much better off moving, but I can't get a straight answer either way, so I'm stuck scouring the internet trying to find similarly situated people to try to get some idea of what life may look like for us in 2-5 years.
