How did you get your Psoriatic Arthritis Diagnosis

Hello, I have guttate psoriasis and have just been to my gp because I am noticing some changes to a bone in my foot and have been suffering for some time with alternate pain in my glutes when I am in bed at night. These pains tend to go when I start moving around. I am wondering if I am developing psoriatic arthritis. My gp took bloods and said I might not be referred to rheumatology unless my bloods showed elevated markers. Any of your experiences would be welcome. Hope everyone is doing ok. Best wishes to you all, Kaye
