My husband has had OVER A YEAR long "UTI" and constant sores on his penis, we have been to the walk in 14 times, each time getting some antibiotic or cream. He's been for blood and urine tests and ultrasounds. Finally a month ago we find he has Serratia Marcescens. He was given Ceftrixone shot and some pills for a week, which did nothing. Then he got the Cefrixone shot daily for 7 days which again did nothing. AGAIN they send he and I for urine tests. His tests read negative, but he still has all his symptoms. Mine says I have Group B Steptococcus, We are so confused and frustrated! What is the cure?! No one seems to know 🙁
