Charlene Lynch, 27, who suffers from Hodgkins lymphoma, also claims she was not fed because staff did not know she was there.
She was admitted to Connolly Hospital in Blanchardstown, Dublin, last Friday, when she required emergency surgery on her foot.
But after the procedure, instead of being sent to a post-op recovery ward, a bed shortage meant she was abandoned in the tiny room and given a curtain for a blanket.
Mum-of-one Charlene, who was discharged yesterday, told the Irish Mirror : “I just couldn’t wait to get out of there. I feel like I’m nothing. I just feel like dirt. My illness hasn’t been taken into consideration or anything.
