Cara McKee: “People don't know about trigeminal neuralgia. It is an invisible illness which I think affects more people than we know.”

It is a little bit like the game Operation where if you touch something you should not it sends out a shock. It is like an electric shock. It is extremely painful. So painful you cannot do anything else.

But if everybody who is in pain doesn't step forward then people in pain aren't going to be recognises and aren't going to have their voices heard. So I thought it was essential.

[The attacks] definitely gets worse when you are in stressful situations. So I did think whether I should really run to be an MSP as clearly I would be in stressful situation were I elected.

It feels like I can't be there for my kids. I can't talk with them.
