Has anyone successfully claimed on an Aviva critical illness policy?

I have psoriatic arthritis (diagnosed ages 30 in 2010), and osteoarthritis in every joint in my hand (2020). I have had an Aviva life and critical illness policy since 2007. It covers rheumatoid but that’s the one I don’t have!

I wonder if it’s worth a claim anyway? 🤷🏼‍♀️

I chose to quit my job in Jan 2020 as opposed to going sick as I didn’t want to mess them around, but I couldn’t cope with the driving and sitting at a computer.

I don’t claim any benefits.
