PMRGCAuk is a registered charity in the United Kingdom which aims to support sufferers and influence research and development. We are committed to furthering the improvement of patient outcomes in Polymyalgia Rheumatica and Giant Cell Arteritis. In particular we want to make sight loss through the late diagnosis of GCA a thing of the past. We are a small organisation that relies almost entirely on subscriptions of members and donations from the public. Founded in 2010, we now operate an online self-help and support forum, a national helpline, an information and advice service, a website, and a network of support groups around the country.
