Prostate is good,no uti,blood work normal burning in perineal area. only have internal hemorrhoid a can this cause the burning?

Nerve pain: Burning in the perineal region can indicate either a skin condition or a possible nerve compression in your lumbosacral spine. It is unlikely that the haemorrhoids are the cause

Haemarrhoid: Internal haemarrhoids can cause itching sensation but not burning , there would be additional reason for burning.

Unlikely: internal hemorrhoids are usually painless.
