Tight Feeling in Chest a Symptom of Psoriatic Arthritis?

I am experiencing a tight feeling in my chest that is very uncomfortable. I had a chest x-ray today and it is clear. I have asthma, but the neb treatments have not given me any relief. I have psoriasis and have recently had my index finger swell to the point where I coundn’t bend it. My brother is on remicade for psoriatic arthritis.. do you think this chest discomfort could be a symptom of psoriatic arthritis?
