Hi walkingthedog - haven't seen you for a while
So sorry to hear you're in hospital and do not yet have a diagnosis but pleased you feel well.
Interesting about the liver cysts because like dangermouse I have them too - several about 2-3 cm in diameter. I wonder if they continue to grow? Mine are benign fluid filled cysts and docs are not concerned so I'm not. Blood tests taken recently for other symptoms have all been normal.
Can you tell us something about yours ie how they dealt with them and what they say the cause might have been?
Sounds like you are in good hands with your docs being thorough and ruling out anything sinister.
I don't really know anything about CRP but I also found as bear did that oral and not transdermal oestrogen increases it.
There are lots of papers around and it seems that it is an "acute inflammatory protein that increases up to 1,000-fold at sites of infection or inflammation ". There is a very detailed paper about it here:
