diagnosed with psoriatic arthritis

Hi I got diagnosed about 6 months ago had 2 steroid injections that didnt work and a oral steroid strong dose that didnt help and now ive been on methotrexate and sulfasalazine for 24 weeks and my hands are worse than they have ever been with joint pain.
Has anyone been through similar and had the next steps or taken anything that has seemed to help?
Thanks in advance.
