Do I have this type of arthritis or is it rheumatoid ?

Hi everyone, I am worried that I have psoriatic arthritis but my doctor is saying it is rheumatoid arthritis. I have a lot of of the symptoms, skin psoriasis ,pitting in my nails, fatigue. I have been taking Turmeric to help with the pain from my arthritis and I don’t know if that is masking my inflammatory markers. Is there any other way I can make sure I am not being misdiagnosed, thank you for any help 🙂
