So, could be many more than you realise.
Very many more.
People living with a physical or mental health problem which cannot be seen look fine. They look healthy. But in actual fact, they are living with something which may be quite horrendous. Something frightening. Something painful. Something which has a huge impact on their life. But....they look fine.
Their disability is already bad enough, without having to then deal with obstacles and prejudice.
Trigeminal Neuralgia and other facial pain conditions are just some of the many invisible conditions. People can be living with unbearable pain, but nothing can be seen. Not even by a doctor.
