Linda Nolan said she was "astonished" by the results of a new treatment for lymphedema.
The condition causes swelling due to a build-up of lymph fluid in the body and can be caused by a variety of things including faulty genes or damage to the lymphatic system, according to the NHS.
Linda, 63, developed lymphedema after having a mastectomy following her breast cancer diagnosis in 2006 and said she's been "plagued" by it ever since.
