Yes, exactly! I think that there's no way to know the answer to that...nerve issues can just appear out of the blue & so can lymphadema ! When I ran the docs opinion that the swelling caused the nerve thing she was skeptical - said that lymphadema swelling is so surface, that it doesn't run deep enough to affect nerves, which are more deeply embedded. But when I mentioned that to the neurologist. she disagreed...So go figure
