Could psoriatic arthritis be a more systemic problem leading to multiple seemingly separate problems to include PACs, prostate/urologic, and multiple areas of tendonitis without strain or injury?

Good day, I am a 50 year old white male. HT: 5’10” wt: 246 lbs. HX: sleep apnea, high cholesterol and triglycerides and HBP. All controlled with medication and cpap. I have also been treated for soft tissue inflammation and arthritic symptoms for several years. My family doctor suspects psoriatic arthritis as a have several small areas of psoriasis. I recently had surgery to remove torn meniscus. My MRI revealed severely thinning cartilage. I also had carpal tunnel release in left wrist along with steriod injection in tendon of right wrist last year. Over the past several months I have developed sub-clinical premature atrial contractions but was cleared for knee surgery with good echo cardiogram and calcium score. I am now developing nodules on tendons on hands causing trigger finger along with achilles tendon nodule that is painful to touch or walk. I also have a nodule on my oppsite foot at the base of my big toe. I have also developed hematuria with restricted urine flow and output. CT scan negative for kidney stones but revealed simple cysts. No elevated creatinin. I suspect enlarged prostate pending follow up with my family doctor. I also have had significant lower back pain for years due to narrow disc space that has gotten alot worse in the past 6 months with the same timing as the PACs and urologic problems.

Could psoriatic arthritis be a more systemic problem leading to multiple seemingly separate problems to include PACs, prostate/urologic, and multiple areas of tendonitis without strain or injury? None of my current symptoms are currently resulting in positive imaging or bloodwork other than urinalyis
