I am a 27 year old male with a longstanding history of chronic abacterial prostatitis or prostydonia. Recently, I starting experiencing very odd sensations in the area of my perinuem, along my pelvic floor, believed to be in the area of my prostate. The sensations are like an intermittent vibration, or quivering if you will. Although not painful in nature, they are very aggrevating and tend to last from about 2 seconds in duration, with a variable amount of time in between each spasm. I have had them occur in intervals of 5 seconds up to several minutes. I am highly concerned am currently trying to make another urologist appointment for help. If anyone has information regarding cause and treatment of this, I would love to know. I have had difficulty finding information from others of similar symptoms. Thanks to all...
