Hello Flyinglow and welcome. Yes, this is a rapid rise and is likely prostatitis/an infection rather than prostate cancer. If you give us dates and PSA score over time we can more intelligently guide you. In the meantime, I suggest you consult a urologist who will most likely put you on a course of antibiotics to see if the PSA rise is infection related and comes down.
We have another relatively new member in the same boat. Here is a thread where members comment on his situation; you might find this helpful.
