Final answer:
Epidural complications include back pain, fever, nausea, vomiting, blood in urine, potential kidney function impairment, and in severe cases, infections that may lead to sepsis.
Step-by-step explanation:
The potential complications from an epidural can include a range of issues, though they are relatively uncommon. Complications may arise such as back pain, in some cases leading to chronic discomfort. Others may experience fever, which might suggest an infection related to the procedure. Nausea and vomiting are also potential side effects. A more serious complication that can occur is the presence of blood in the urine, which may indicate potential scarring of the kidneys or impaired kidney function. In severe cases, infections that develop after an epidural can lead to sepsis, a serious condition that can be life-threatening if not treated promptly.
