I just received blood test results. My PSA has gone
It is probably nothing
I am sorry to hear about your distress. It is important to keep in mind that the PSA, like any other test, is subject to some degree of uncertainty and periodic changes, that are not associated with disease. Many things, like UTIs, can affect the PSA, so I would also recommend having a retest. Sexual intercourse may also influence results, to some extent. If the PSA remains high, you should have prostate biopsies taken.
Hope this helps.
