Welcome to HW,
PSA isn't a test for cancer. Just tests prostate activity. Many things can rise PSA, infection, BPH (enlarged prostate), sex before the test, bike riding, shifts in the tide and bad days at the lab. Your PSA while not good, isn't alarmingly high. That much of a rise in a year is notable. Generally you don't do a biopsy until you rule out all other factors.
PC at this PSA normally doesn't have symptoms. Having BPH could explain both your symptoms and PSA level and in my thinking the more likely problem you have. Your hip pain is more likely due to being 57. Bone pain due to PC would be constant and would not resolved with stretching.
But, I am not a doctor, just some random guy on the internet.
As for the biopsy - well it's annoying, uncomfortable and undignified but not painful. You will feel a bit of a punch when they take the sample and of course will have a probe up your back side. Post biopsy you'll have some discomfort, bleeding and blood in your urine and seamen for awhile. It can take a week or two to get the pathology report back.
Hang in there and keep us updated on your progress.
I'll be in the shop.
