What are the symptoms of UTI?

Not everyone with a UTI has symptoms, but most people get at least some symptoms. These may include a frequent urge to urinate and a painful, burning feeling in the area of the bladder or urethra during urination. It is not unusual to feel bad all over — tired, shaky, washed out — and to feel pain even when not urinating. Often women feel an uncomfortable pressure above the pubic bone, and some men experience a fullness in the rectum. It is common for a person with a urinary infection to complain that, despite the urge to urinate, only a small amount of urine is passed. The urine itself may look milky or cloudy, even reddish if blood is present. Normally, a UTI does not cause fever if it is in the bladder or urethra. A fever may mean that the infection has reached the kidneys. Other symptoms of a kidney infection include pain in the back or side below the ribs, nausea, or vomiting.
So you see there are things in common here. I do suggest you see a doctor who will do blood tests and urine analysis so that you can get the proper care.
And not many people at your age get prostate cancer, a test was done with the following results :
spots of cancer were present in 8% of men in their 20s, 31% of men in their 30s, and a further increase with each decade up to 80% of men in their 70s. These cancers were incidental, ie, they had not presented with clinical manifestations. Thus, incidental prostate cancer is extremely common in aging men, but may also be found in young men.
I hope this answered your question. All the best to you.
