The Rheumatologist can help with your joint pain, swelling, fatigue etc. All the things that go along with Psoriatic Arthritis. Let them know what you are taking now for your Psoriasis and any past treatments. Tell them about all of your pain, swelling, fatigue and even your emotional struggles...
Good luck.

He helps with my pain.

I’ve been seeing one for about 4 years now. He’s helped me quite a bit for my arthritis pain, and he listens to me.

I don’t see a rheumatologist, I believe they help with pain in your joints, like psoriatic arthritis. But some of what they prescribe will also help your psoriasis

I've been seeing one for several years. I think it would help you Sweetie.
