Hello and thanks for your query. I shall make an effort to provide you with good professional recommendations specific to your questions. As he is having burning sensation, I advice you not use coconut oil with essential oils of eucalyptus and lavender as a lubricant. Observe is there any improvement. I advice him to have plenty of fluids and take cranberry juice, as this is found to be helpful in urinary tract infection. I would have advice you to follow this for week and if there is no improvement, would have gone for urine routine and based on the report next action can be considered. Yet again, I duly appreciate your query to me, I do hope that you have found something useful to help you and I shall be glad to answer any further apprehensions. Sincerely,
