For 6 I've had prostate issues even had biopsy at 39 PSA was 3.9 test was neg. The last two years PSA. 7 with free PSA 26%. Still symptomatic some days worse than others. Worried Drs missed cancer.

Falling PSA is good. Previously elevated PSA was likely due to inflammation, infection or manipulation. Your PSA is now within normal limits and biopsy was negative. All is OK & suggest you stop worrying. There is plenty of real stuff going on round the world to worry about, but, fortunately not your prostate.
Many causes. symptomtic can mean many things. Further testing may show a non cancer issue responsible for syptoms.
