Hello everyone! Does anyone know if pleurisy is classed as a disability. I developed pleurisy in December 2014 after an operation, then coming down with flu and then pneumonia. At the the time I was in university doing my third year as a mature student. I had to give up the course and still now I have difficulty breathing when I am out shopping or going out with my kids and wife. The pain is bearable and not chronic, can anyone give me some advice please!
