ESA claims

I have a Urostomy which is a bag where my urine is emptied, it’s known on the ESA WC form as a collecting device. I get up to 5 leaks per week. Will this put me in the non working group?

I also have arthritis and cervical disc disease. I problems sitting for longer than 30 mins to an hour, however I can stand and walk. How can give an example as the WC form puts standing and sitting together, which in my opinion is not fair., as some people like myself might only be effected by one.
