Psoriatic Arthritis meds

Hi all, Can anybody give me any advice on meds for Psoriatic Arthritis.? This is my Experience . I got referred to a rheumatologist early this year. The rheumatologist diagnosed me with PSA and put me on methotrexate first off i was on 15g then after 1 month they put it up to 20g. I had a bad experience with methotrexate did not work i went back to the doctors they didn't belive me, I had told them it was making me really ill. I decided to just stop taking them. I moved house from England to Wales and had to change doctors. I went to the doctors and described my pain and they once again referred me to the rheumatologist. I have now had the appointment with the new rheumatologist yesterday went through the whole process again . I told them my experience with methotrexate and i did not want to take them again instead they had given me an anti inflammatory to try naproxen 500g they said they would like to see how i get on with naproxen before they will put me on sulfasalazine, they told me they had to try 2 DMARDs before they can give me biologics . Has anybody else been on naproxen for their PSA ? my rheumatologist. sent me for x rays and blood test just waiting on results. I am worried that my PSA is taking over me and they are just trying to palm me off. I get a lot of pain in my hands and they are swollen i have numbness and tingling in them and lose grip very easily. I have sausage digits fingers and struggle to bend my thumbs, Morning stiffness is unreal i find it really hard to straighten my legs out. my toes are just like my hand i cannot bend the big toes. Very recently i have been experiencing some pain in my shoulder blades very sharp pain and muscle cramps. also i always feel fatigue. the bottoms of my feet feel like they are burning. I get days where i get down and just want to give up especially when i cannot open a can or a bottle. I am intrigued to reading some of your experiences.
