Hello Aspyn and Welcome!
Newbie to the forum here too.Glad that you have a good rheumatologist that is prepared to work as a team.
I was only diagnosed with PSA December last year,despite having chronic Psoriasis since I was 7,I'm now 50.
Been started on Otezla,and just added Methotrexate.
I sincerely hope that your pain continues to be reduced to a manageable level.
Hi ouch! Welcome to you as well! How are your meds working for you (if you don’t mind me asking?)…being new here, I am looking to gather as much info as my brain can handle, so that I can pepper my Dr. With questions about all the options 
I hope all of us newbies get some pain relief and feel better soon. I hope we will become as well versed as the others on this site with management of all of our symptoms and pain.
