Can Fear Possibly Cause Anxiety?

Anxiety can be debilitating and impact your ability to function each day. Too much of it is overwhelming and will start to take a toll on your health and wellbeing.

As is the case with many other mental health conditions, you can’t see anxiety, so there is interest in what causes it and why it manifests itself. One theory is that fear causes anxiety. Although fear and anxiety are responding to different dangers (real vs. imagined), they are interrelated.

You could say that fear causes anxiety, and anxiety causes you to feel fearful. It’s worth taking the time to dive deeper into fear and anxiety and learn more about how the two are connected.

Stress Response

The truth is that both fear and anxiety produce a stress response to both real and perceived danger. You may begin to feel muscle tension, an increased heart rate, and shortness of breath. The stress response prepares your mind and body to react to a danger signal, which will set you up to flee or to fight when you’re faced with an unsettling situation. The stress response includes physical and thought responses to your perception of various situations and works to keep you safe.


Fear is a response to a known or definite threat. It’ll make you run for cover and ignite the fight or flight response. There is a clear and present danger, and your mind and body begin to respond to this fact. Fear is real, definite, and immediate, which may make you feel anxious and jumpy.

Most people will experience physical reactions that are similar to those that manifest as a result of anxiety when faced with fear. However, there are subtle differences between the two, which are important to note when trying to deal with and treat fear and anxiety. Fear may even transform into feelings of anger and mixed emotions.


You can define anxiety as a diffuse, unpleasant, vague sense of apprehension. The threat may be imprecise or unknown but still causes you to have a response to it. Anxiety is tied to the possibility that a bad or frightening event or situation may take place in the future.

It’s not a result of a known and specific threat. Your mind begins to worry about all the dangers that may arise and try to prepare you for the unknown. It’s important to remember that anxiety can also be an appropriate response to a situation and a source of strength. The issue occurs when it takes over and starts to cause you more harm than good.

Treating Fear & Anxiety

Many mental health conditions arise from having too much fear or anxiety. You must get help from a professional if they’ve become unmanageable and are interfering with your daily functioning. You’ll be able to share more information about your symptoms and past history to get a better idea of what may be causing and triggering your fear and anxiety.

There are several treatment options you and your medical professional can discuss. When exploring how to treat anxiety, you will learn about therapy and medicines that can be prescribed. Another option is the stellate ganglion block injection for anxiety treatment, and it has shown very positive results.

The SGB shot for anxiety treatment consists of an injection of local anesthesia administered on the stellate ganglion, a cluster of nerves on the neck. This cluster is part of the body’s sympathetic nervous system and triggers the “fight or flight” instinct in the brain. People who suffer from anxiety have an overactive stellate ganglion that constantly sends “fight or flight” signals to the brain, overwhelming it. The more overactive the cluster of nerves, the stronger the anxiety.

The stellate ganglion block for anxiety therapy (SGB) helps quiet the stellate ganglion. To accomplish this, the procedure is performed while guided by X-ray, ensuring that the anesthetic is placed on the proper spot. Results are usually quick; the SGB injection for anxiety often relieves symptoms in as little as 30 minutes.

The results of SGB for anxiety and depression can last for years. Once its effects subside, it can be re-applied by a PTSD doctor near you. The injection for anxiety relief has a high success rate, meaning that the reapplication has a very high chance of working as well as before.

To find out what your options for anxiety help are, seek out a clinic that offers the SGB for anxiety near you.
