Hi Nathan
Welcome to the forum.
You might want to have a look at the following FAQ which explains where everything is;
www.benefitsandwork.co.uk/guides-for-claimants/faq/forum I would not concentrate on long covid but on how your condition(s) affect you when you complete the UC50 form, read our guide to complete UC50 form;
help-for-claimants/esa1 Long covid varies and they are still learning on how the condition affects each individual, each individual is different. I myself have had long covid for nearly 2 years, so I can tell you from personal experience that my condition changes on a daily basis, all you can do is try and explain how it affects you, along with your other conditions.
