Does an epidural needle hurt?
The physician anesthesiologist will numb the area where the epidural is administered, which may cause a momentary stinging or burning sensation. But because of this numbing, there is very little pain associated with an epidural injection. Instead, most patients will feel some pressure as the needle is inserted.

Disposable Medical Epidural Tuohy Needles
Why are epidural needles so long?
And the size is also crucial. "Epidural needles are long so that we get better access to the epidural space," the medical student told the site.
The skin is anesthetized after the bony landmarks have been identified. The epidural should be placed at the dermatome of the surgical incision, which usually lies between T5 and T9. The midline approach to the epidural space passes successively through the skin, subcutaneous tissue, and supraspinous and interspinous ligaments and into the ligamentum flavum. The steeply overlapping thoracic spinous processes require a comparable needle angle. The depth of the vertebral canal from the skin varies depending on the level in the vertebral column, amount of subcutaneous fat, body size, and needle angle so that no safe rule of thumb can be applied. Because the ligamenta flava are steeply arched, the vertebral canal is entered about 1 cm more superficially in the midline than laterally, adjacent to the facet joint. The ligamentum flavum is 3 to 5 mm thick in the thoracic region versus 5 to 6 mm in the lumbar region. If needles are kept in the midline, the ligamentum flavum is perceived as a thicker ligament than when needles are allowed to be inserted off the midline and entered at the lateral extension of the ligamentum flavum. The problem is that the spines of T5-8 tilt significantly downward, making a midline approach to the epidural space practically impossible. This would necessitate a paramedian approach instead of a midline approach.
