3 years after being diagnosed - No access to Biologics

Hello,
English is my second language so apologies for any typos.
I'm 32 years old almost 33 in 2 weeks. I was diagnosed on 2019 with a mild psoriatic arthritis after several months with a really acute lower back pain.

As many other cases when they brought up methotrexate, I went missing in action, until my next flare up. Then I crawl back to my doctors office with greater pain, and looking for anything that would ease my pain.

I live in Dominican Republic, and the access to biological specifically Humira is very limited, and almost exclusively through a government plan.

I was able to get a 3 month treatment, and it worked really well. Completely pain free. However I had to stop Humira after the third month due to shortage of the medication, and since then I had been getting inflammation in many new joints first it was lower back pain, then feet, and hands, now TMP, chestpain, and recently after a throat infection, I got a very strange swelling on my throat. After several studies they showed Cricoarytenoid swelling.

My question is what options do I have if my access to biological treatments are this limited? Is there any other treatment with more accesibility? Most of the time the pain is so manageble that I dont even need anything else, but since I have seen so many new joints are being affected, I'm starting to fear the progressing is advancing rapidly.
