Every day is a struggle

My partner Stuart 39 has psoriatic arthritis. He was diagnosed in 2016 after years of attending doctors and hospital appointments. At the point of diagnosis he was struggling to walk or care for himself due to pain and stiffness. Stuart started methotrexate September 2016 and weekly physiotherapist sessions. The progress was amazing, he was looking healthy and life was beginning to look positive until Aug 2017 when he began experiencing excruciating pain in his ankle. We went to the doctor, had 3 X-rays and Stuart was told they couldn't find nothing wrong and was basically fobbed off like some kind of hypercondrac. Stuart was exasperated, he felt low and his quality of life detiriated once again. After his January rheumatology appointment was cancelled we both gave up hope as everyday he was getting worse and his ankle became severely deformed. Eventually after seeing his rheumatologist in July he was immediately referred to orthopaedics. Now 4 months later it's been confirmed stuart has suffered avascular narcosis. The bone in his ankle is dead and completely clapsed. He can't walk or look after himself and we now face up to 5 months wait for surgery. We try to stay positive but it's getting harder
