Does Epidural Steroid Injection Cause Water Retention

epidural steroid injection (ESI) is a popular and effective treatment for various types of pain. However, ESI is not without risks, one of which is water retention. Careful monitoring is important to prevent water retention following ESI, as it can lead to serious complications such as brain damage and even death. In this blog post, we will discuss the danger of water retention and how you can prevent it.

What is Epidural Steroid Injection?

Epidural steroid injection is a therapy used to treat various conditions, including chronic pain. The injection is administered through a small hole in the spine and numbs the area around it. This reduces the feeling of pain. Epidural steroids are often used together with other treatments, such as medication and physical therapy. The injections can help reduce the amount of pain that a person experiences. There are several potential side effects associated with epidural steroid injection, including water retention. This can be particularly problematic if it occurs in areas where there is already excess fluid accumulation, such as the abdomen or thighs. In extreme cases, water retention can lead to edema (swelling), which can be dangerous and cause long-term damage to tissues.

What are the Side Effects of Epidural Steroid Injection?

Epidural steroid injection can cause fluid retention and edema. This is due to the fact that epidural steroids work by decreasing inflammation in the spinal cord. They do this by blocking nerve impulses, which reduces the swelling and pain associated with spinal cord compression. Epidural steroid injection can also increase the risk of infection, which can lead to further increases in fluid retention and edema.

Can Epidural Steroid Injection Cause Water Retention?

Epidural steroid injections can cause water retention, which may lead to swelling in the lower extremities. This is most likely to occur in patients who have preexisting conditions that increase their risk of developing fluid retention, such as heart disease or diabetes. In some cases, the water pressure inside the veins surrounding the spinal cord increases, causing blood cells and proteins to leak out into the surrounding space. This can lead to inflammation and kidney damage.

What to do if You Suspect Epidural Steroid Injection Caused Water Retention

If you are concerned that an epidural steroid injection may have caused water retention, there are a few things you can do. First, consult with your healthcare provider to get their opinion on the matter. They may be able to tell you more about the injection and whether it is likely to have caused the water retention. Additionally, if you experience any of the following symptoms, speak with your healthcare provider immediately: swelling, fluid retention, chest pain, shortness of breath, or dizziness. If these symptoms persist or worsen after consulting with your healthcare provider, you may be experiencing signs of complications from water retention and should seek medical attention. In some cases, treatment for water retention can include using medications such as diuretics or surgery.


Epidural steroid injection is a painless procedure that can help relieve various types of pain. However, some people have developed water retention as a result of the medication. If you are experiencing swelling and/or fluid accumulation in your tissues, it is important to speak with your doctor about whether or not epidural steroid injection is right for you.
