Need expert help here. what are the risks of epidural?

Many. Big vs. common: I will skip the common risks, because they usually discuss these with you before proceeding. The most serious risks are all < 1 in 30, 000: if you have certain heart conditions your blood flow could stop. If you are taking blood thinners, you could become paralyzed from uncontrolled bleeding in the spine. If you are unlucky, you could get a major infection. Common risks are not as serious.

Risks: Many risks are issues with any procedure including bleeding, infection, nerve damage and paralysis. These are rare and very often never seen in properly trained physicians such as fellowship trained pain specialists. Also make sure they use fluoroscopic x-ray guidance to verify location. Typically epidural helps with leg and back pain but can be helpful in back pain alone.
