I Had High Dosage Rate Brachytherpay On 11/6/15 For PCa.

I had High Dosage Rate Brachytherpay on 11/6/15 for PCa. and now I have some numbness in my penis. I believe this is transient because I have been paying close attention to my body, and it is beginning to come back online. Aside from LCarnatine and Vitamin B Complex supplentns, what my I add to my diet to mitigate radiation damage to my penile nerves?
