question: I have a numb penis head and pain in the right buttock cheek. With constipation. A little tingling down the right leg. I am having trouble urinating. Last night the doctors gave me diloden and the urination issue went away. But now it is back. I have been in chemo for the last eight weeks. Revlimid and kyrlyso.??? Mixed with dexamethasone . Twice a week. Tingling and numbness are new feelings this week.
