Since yesterday my mom feels really dizzy, but only when laying down.. when she's seated or standing she feels okay.
She get's panicky so she doesn't want to lay down flat, only upright with a few pillows under her head so she doesn't feel dizzy

We're on holiday in Portugal now so really difficult to go to the hospital and she doesn't want to go.
I'm worried has anyone else had something similar were you feel dizzy but ONLY when laying down flat?? please help...
