How do i know if i have either a bladder infection, kidney infection or uti? what's the difference? what are the symptoms of each?

Anatomy: All infections involving urine are uti's (urinary tract infection). Kidney infections, or pyelonephritis are a type of severe uti. Cystitis, bladder infection or common UTI is a usually less severe type. Urethritis is infection of the urethra, it's also a uti. www.peedoc.com @thepeedoc.

Symptoms: A UTI (urinary tract infection) is a general term for any infection within the urinary system. Bladder infection is also known as cystitis. Kidney infection is also known as pyelonephritis. Typically, patients are more ill when they have a kidney infection compared with a bladder infection - fevers, nausea/vomiting, abdominal and back pain.
