Hi, my name is Anatona! What benefits can I claim?

I have suffered with back pain for 34 years. In 2014 I was diagnosed with Inflammatory arthritis. Five years later I sought a second opinion and was given a diagnosis of Fibromyalgia. I now also have Osteoarthritis and am currently being investigated for Rheumatoid arthritis, specifically in my feet and ankles.Last week I was diagnosed with prolapsing discs in my lumber region and Facet joint syndrome. I have previously also been diagnosed with a bulging disc in my neck. I currently am only able to work 12 hours a week in a local pet shop, but am finding that I am in extreme pain after standing for four hours. Are there any benefits I would be qualified for to help us financially?
