Hello doctor: I have been suffering from prostate enlargement for 2 years now taking medicine continuously: Recently I feel pain, a little burning in the lower abdomen around the pubic bone; frequent urination 4-5 times a night. I went for a prostate ultrasound examination of 30 grams; quantitative test results for total PSA 0.68 ng/mL (higher than 4.1 allowed); Free EPSA 0.28ng.mL.
