Could it be?

Hey everyone I’m new here. I’m Lisa 35 and have suffered from psoriasis for 25 years now. I was in an accident in 2009 which left me in pain pretty much every day since then, I’ve had numerous xrays in the past which they said I have bone spurs that are trying to fuse over. I had trouble with “flare ups” during my monthly cycle so the Dr recommended a hysterectomy. Had that in April this year yet still have flare ups almost every month. Every day I am stiff in the mornings and in pain with my back and pelvis/hip and also get frequent knee flare ups. My nails are also really bad to the extent I no longer wear them natural as they are so thick and pitted and coming away from my nail bed. I also had my big toenails removed because of it a few years ago. I got fed up after my recent flare up that I googled my symptoms (I know I shouldn’t) and it pointed me to the direction of psoriatic arthritis. I went to the Dr who done blood tests that have came back okay however he is sending me to see a rheumatoid specialist. Could this be the answer to why I feel like this? Any feedback would be great. Thank you in advance.
