Thank you for your question to HCM.
A slipped disc
is never a cause of urethritis
. It would be more helpful if you describe your symptoms more elaborately. It is not clear from your description how a diagnosis of urethritis was made. Nerve compression from a herniated disc
can sometimes lead to urinary incontinence
and dribbling as well as numbness in the genital area. However a disc never causes urethritis.
Hope this is helpful. Take care.
