A spokesperson from Gloucestershire Hospitals NHS Foundation Trust said: “We are sorry to hear that Ms Smith continues to experience ongoing pain and the impact this is having on her quality of life.

“Ms Smith’s case continues to be taken seriously.

“She has been seen by a number of consultants and has undergone investigations as part of ongoing efforts to better understand and address the symptoms of what is a complex clinical picture.

“We are aware that Ms Smith has raised concerns about aspects of her care.

“We continue to investigate the issues raised through our formal complaints process and will continue to work with Ms Smith to address her concerns.”

Smith said she was hoping to raise £95,000 for a private bilateral jaw replacement – a surgery that involves replacing the joints between the lower jaw and the base of the skull.

She said the surgery “wouldn’t make the pain in my whole body go away but it would mean I could finally eat and chew again, and it would mean the world to me”.
