Symptoms that may accompany epidural needles:

1. Nausea and vomiting, visual disturbances, hearing changes, etc.

2. Causes of visual impairment: temporary paralysis of the extraocular muscles innervated by the oculomotor nerve (ie, the 3rd, 4th, and 6th cranial nerves). The 4th cranial nerve is the most commonly affected nerve because it travels intracranially. Longer, epidural blood patches can improve symptoms.

3. Hearing damage: mainly occurs in the low frequency range, because the loss of cerebrospinal fluid causes the pressure of cerebrospinal fluid to drop, and it is transmitted to the inner ear.
