<s>[INST] Hi, I have a painful pins a needles sensation down the length of my penis.  Im 26 years old and have two disc injuries in my spine after a car accident four years ago, which has also caused nerve damage to my bladder.  I also have high blood pressure.  What could this sensation be? [/INST] Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. No nerve damage to bladder won't cause pain after a so much time. If you receive a pain immediately after injury than we can count it because of injury. This type of sensations are common in nerve regeneration, so if your damage nerve are getting repaired than you can have such a feeling. In my advice you should take tab pregabalin, tab vitamin B complex. This will help in recovery from such a problem. Please do perineal muscle exercise in other word stop and release urinary sphincters as much time in the day as possible. This will help recover fast from the problem you are having. Some physiotherapy and electrotherapy can also cure such a problem. You can visit nearby physiotherapist they can guide you regarding exercise. I will be happy to answer your further concern on bit.ly/ Chat Doctor. Thank you, ChatDoctorInfectious diseases specialist, ChatDoctor. </s>
