When to Seek Emergency Care


If you have symptoms of an allergic reaction, do not hesitate to come to The Emergency Center. Most allergic reactions could warrant an emergency room visit, some emergent symptoms could include:

  • Severe Difficulty Breathing: If you’re struggling to breathe, it could be due to anaphylaxis or severe airway constriction, necessitating immediate medical intervention.
  • Swelling of the Face, Lips, or Throat: Swelling in these areas can obstruct airways, posing a life-threatening situation that requires urgent care
  • Rapid or Weak Pulse: An irregular pulse can indicate cardiovascular involvement in the allergic reaction, needing prompt attention to stabilize your condition.
  • Widespread Hives or Rash: Extensive skin reactions might signal a severe allergic response affecting multiple body systems, needing emergency treatment.
  • Nausea, Vomiting, or Diarrhea:Severe gastrointestinal symptoms can be part of an intense allergic reaction, especially with food allergies, requiring immediate care.
  • Confusion or Loss of Consciousness:These symptoms can indicate a critical drop in blood pressure or severe lack of oxygen, calling for urgent medical response.
  • Tightness in the Chest or Throat:This could be an early sign of anaphylaxis, which requires immediate intervention to prevent further complications.
  • Difficulty Swallowing or a Sense of a Lump in the Throat:This could suggest significant swelling in the throat, potentially leading to airway obstruction.
  • Persistent Dizziness or Lightheadedness:These symptoms might indicate low blood pressure or shock from the allergic reaction, needing rapid stabilization.
  • Severe Abdominal Pain or Cramping:This could signal a serious allergic reaction affecting the gastrointestinal system, requiring immediate medical attention.

What Our Patients are Saying About Us

My visit to the emergency center of San Antonio was amazing. I was seen right away for sciatica pain. Dr. Styskal was amazing. I was treated right away and sent home with my medication. I wish more facilities would practice this without you having to make an additional stop at a pharmacy for medication. I know five stars is the highest I can give but they deserve 100+ stars.

I was skeptical about going to the Emergency room, because for me ER’s have a bad reputation. My experience here was one of the best experience I’ve ever had. Keith at the front desk was very nice and went above and beyond for me. I forget my insurance card and wanted to know how much my co pay would be. He looked me up with no issue, brought my a wheelchair to ease my pain, as well as started

Mecia T. ★★★★★

My first time coming here, was greeted immediately by Keith and Debbie and helped. When in the back, Nichole wasted no time getting my vitals, checking on how I was feeling, and was super friendly and comforting while doing so. Dr. Erdner was very nice, and informative. Johnny got my CT scan quickly and made the process easy, and fast. All together the staff made my visit a great experience.
