When to visit the ER

Sometimes it can be hard to know when you are facing a medical emergency. Stomach pain and headaches are two of the most common reasons people go to the ER, but how do you know when you should seek emergency care right away? The following are symptoms you should check for if you are considering a visit to the StoneSprings Hospital 24-hour ER:


The flu is very common, but for certain high-risk populations, it can pose a very serious threat. High-risk populations include infants, people 65 years old and older, pregnant women, people with certain diseases, such as asthma or chronic obstructive pulmonary disease (COPD), and people with weakened or compromised immune systems.

If you have the flu and are experiencing any of the following symptoms, you should go to the emergency room:

  • Trouble breathing
  • Vomiting that can’t be controlled, to the point of severe loss of body fluids and dehydration
  • If you develop complications such as pneumonia

Head Pain

If a sudden headache prevents you from performing daily tasks, is significantly debilitating or is accompanied by the following symptoms, you should go to the ER:

  • High fever
  • Difficulty walking
  • Severe pain that begins suddenly
  • Neurological symptoms including weakness, numbing, slurred speech and blurred vision

Individuals with certain medical conditions may also be at serious risk. If you are experiencing any of the below conditions along with your headache, you should immediately visit the ER:

  • A headache immediately following a head injury
  • If you are taking blood thinners
  • Recent head injury or trauma

Severe stomach pain

Stomach pain is the most common reason that patients visit the emergency room. Stomach pain can result from a variety of reasons and occurs in varying degrees of severity. You should seek immediate emergency care if your stomach pain is accompanied by any of the following:

  • Stomach is hard and/or tender to the touch
  • Persistent nausea or vomiting
  • Inability to eat without nausea or vomiting
  • Pain in your chest, neck or shoulder
  • Shortness of breath or dizziness
  • High fever
  • Irregular heartbeat
  • Dark or black stool
  • Vomit contains blood

Trouble breathing

Trouble breathing, or respiratory distress, may result from a chronic condition like asthma or something as serious as heart failure. If you are experiencing any of the following symptoms you should seek emergency care:

  • Severe shortness of breath that affects your ability to function
  • Noisy, high-pitched and rapid wheezing
  • Coughing up blood
  • Inability to speak comfortably and sustain voice while at rest

What to expect at the StoneSprings ER

Upon visiting our ER, a triage nurse will ask you about your symptoms and take your vital signs. Once you have seen a healthcare professional, a registration clerk will gather information for your medical record and insurance. Whether or not you have insurance or are able to pay, you will be medically screened, evaluated and stabilized.

If you have a life-threatening condition, you will be treated first, followed by seriously ill or unstable patients. Otherwise, you will be seen in the order that you arrived.

Things to bring with you to the ER:

  • List of medications you take
  • List of known allergies
  • A copy of results from any recent medical tests
  • List of recent medical procedures
  • Care preferences and restrictions
  • A responsible adult or phone number for someone to contact

Be sure to ask any questions you may have before you are discharged and keep all paperwork, instructions and medicines, if you received any. Your primary care provider will be given a copy of your visit summary.
