Prostate/perineum area twitching? painless, no other symptoms. happens few times daily, and been happening for about 2 weeks. should i be worried?

Here are some...: Continue to watch and wait so to see how such may evolve and change in its frequency, duration, and interval, etc. for additional 1-2 months, and bring the record of your observation to see doc + physical exam + testing as needed. Clinically, nerve-related fasciculation of muscles may be blamed like that in per-iocular muscle twitching. More? Seek evaluation or counseling.
