Hello Thanks for writing to HCM I think pus discharge is due to urinary tract infection. He need few investigations like routine hemogram,RBS,RFT,urine RE/ME,urine culture and sensitivity,Ultrasound of abdomen can also be done. There are number of causes for red itchy spots on the penis depending on the size,number,distribution,any pain or itching. Red sores may be due to many reasons.It may be due to infection,allergy etc. Infection is usually due to fungus whereas allergy may be due to sweating,lubricants etc. In these cases itching should be treated with antibiotic, antifungal,antiallergic or steroid cream. If they still persist than it s perhaps a condition which needs to be further investigated. He should try to keep the area dry.It is important to wear clean and dry underpants to prevent further infection.He should regularly clean the collection(smegma)present undersuface of prepuce. He shouldn t scratch the area. Hope i have answered your query. Take Care Dr.Indu Bhushan
