Is It Inflammation/Prostatitis or Metastasis

hello, good people. i'm starting to get a bit frightened. as some of you know, i had my 1st. PSA blood test after having HDR treatment. my treatment was done on jan 9th and 23rd of 2020. during july, i was sched to have my first check-up, but because of COVID-19, my RO said i could wait another 6 mths. well, this past january 21st. was six mths. and my blood test came back as i stated was a 4.04, down from a 12.68 in october 2019.

when i ask'd your thoughts about my new PSA score (which i'm always grateful for) i got mixed reviews. but here's the kicker, the last few days, i've noticed some level of discomfort in my lower left pelvis area and my left hip bone. i'm starting to wonder if that's the cancer spreading, is it in my head, or is it inflammation from prostatitis.

back in 2014, i was diagnosed with both BPH and prostatitis. so, i'm confused. i'm afraid that my PCa may be spreading. if i had to grade the level of discomfort, i'd say it would be between 4 and 5...it's noticeable, but NOT excruciating. so, i'd like to know from you guys am i worrying over nothing or is this a sign?

i go back to my RO on tues., march 16th, for another PSA blood test. i'm quite concerned.

It looks like you had a nice drop the first year. I dont know what you expected but it takes a while for PSA to fall to its nadir. Certainly more than a year. Many take several years, with some bounces along the way.
As for your concern of a spread to the hips, my Uro told me once when I expressed a similar concern that a study he'd seen of 20,000 men with PCa with varying levels of PSA in which only 3 had spread to the bones with PSA under 20.

Like Stephen, I was also going to suggest seeing a 'regular' doctor and discussing the pain issue with him. I hope that (s)he will put your mind at ease.
