Pudendel Nerve issues. To diagnose it?

What are the diagnosis find out about the issues with my Pudnedel Nerve.? Don't Judge me.. I am actually gone through all other ways to find out the cause of my following symptoms 1. Vaginal irritation (sometimes on Clitoris, some times in vagina sometimes too much sometimes less) 2. Hypersensitive Bladder (when the irritation is more sensitivity is also more) 3. Occasionally sharp pain on Clitoris. 4. Sometimes back pain near tailbone area. 5. Sometimes Numbness near tailbone area. These issues are making me crazy, I have consulted many urologists, gynecologists, and general physicians.. none was able to give me any relief from this. These treatments , tests and diagnosis are happening from last 1.5 years ... No use.. Now my expectations is on neurologists.. Is this what i think? Or any other suggestions? If it is something related to pudendel nerve, how to diagnose it? Thank you Vineetha
