the index finger on my right hand has been twitching a lot for the past few days. could this be associated with prostatitis?
Not trying to diagnose you because no one here is qualified to do that. My opinion you are trying to associate everything you feel with your prostate, and by doing so just making it worse. I've been in your shoes. The more you focus on your symptoms, the worse you will feel. Anxiety will increase every single symptom you have. If you can get your Dr to prescribe something like Ativan it will help you cope with this.
No matter how you approach your problem, the first thing you need to do is reduce your level of anxiety.
