Help does this sounds like PsA?- rheumatologist reluctant to commit

Hi in 2016 I was diagnosed with RA on the grounds I had a raised anti-ccp level. I was treated with triple therapy but was allergic to the Dmards. I was then seen again and told I had no evidence of RA, that the pain in my elbows looked like tennis elbow on the left and golf elbow on the right and though I had fluid on my knees and ankles my joints looked okay so I should go away an forget about it all - by this time I could hardly walk! I complained, saw another consultant who did a blood test and confirmed I tested positive for the HLA-B27 gene. My father we believe did have psoriasis and I have a history of scalp problems. The disease seemed to calm down in 2018 but now I have severely swollen ankles with what looks like fluid round the joints, swollen Achilles tendons on both sides (i have had this on and off for a long time too), swollen knees and painful ankles. My toes and fingers are also painful and my hands swollen. Despite me and other people saying my fingers are swollen the rheumatologist tells me they aren't as they are the same size all the way down and don't have swollen areas around the joints. All I know is I cannot get rings on my ring finger that I used to wear on my index finger! I have also had back pain for many years along the sacro-illiac joint. My private physio treating me for muscular skeletal issues as I was told my constant shin pain was due to shin splints has written to the consultant to say in her opinion none of this is skeletal and is instead related to some kind of inflammatory process. I have been put on a short course of oral steroids again which don't make a massive difference something that again I'm being told shows it can't be inflammatory except they have no idea why I have accumulated all this swelling around my joints. I'm sorry for the lengthy post. I feel my symptoms and blood results point in the way of PsA but I feel like I'm being fobbed off as my symptoms don't match the usual RA spectrum. When I was initially sent on a course to learn to live with my rheumatoid arthritis before they decided I didn't have it, they showed us the signs and symptoms of the various inflammatory arthritis and I said I thought my symptoms did not match RA but did match PsA. I was told I was being silly as I could not have it as I did not have any obvious psoriasis!
