The new, tougher expenses regime is damaging MPs' "mental wellbeing", the doctor who looks after them has said.
Dr Ira Madan told a committee looking into the system that its "frustrations and difficulties" had increased workloads but decreased rewards.
She also said MPs were tired of being the butt of jokes about their expenses.
And she said they were coming under greater pressure because of the "increased ability for constituents to readily contact members by email".
Following the expenses scandal of 2009, the Independent Parliamentary Standards Authority - Ipsa - was set up to more closely monitor MPs' allowances.
But MPs have complained that the new system is costly and bureaucratic, and has left many of them out of pocket.
They also complain of constant expenses jokes.
"If they go to the hairdresser people will say 'Are you going to put that on expenses?'. It might be funny for the first one or two times but actually it gets right up their noses," she said.
Any Brits got one iota of sympathy for them?
Whining about something that would not have been necessary at all if they hadn't permanently had their hands in the taxpayers pockets seems to me a bit thick when you consider what everybody but the rich in the UK is having to put up with financially.
"We're all in this together"...my arse! Not if they can keep themselves out of it!
