What is a Game Engine? Is it necessary to use one? A. Think of a game engine as a set of development tools that bundles essential functions required for making games, similar to a car engine. It includes features like rendering graphics on-screen ( Rendering ), physics effects for characters colliding with walls or jumping ( Physics Engine ), and playing background music or sound effects ( Audio System ). While it's possible to create a game from scratch without an engine, it requires an immense amount of time and effort, which is why most developers today use game engines, especially beginners! Q2.

Back Pain, What You Need to Know: 5 Key Q&A

Q1. How common is back pain?

It's actually very common. About 7.8% of the global population is experiencing back pain right now, which means approximately 570 million people are feeling the same pain. It's considered one of the biggest causes of decreased quality of life.

Q2. When should I rush to the hospital?

This is really important. If you suddenly have trouble controlling your bladder or bowels, feel weakness or numbness in your legs, or experience a loss of sensation in the saddle area, it could be 'cauda equina syndrome,' and you should go to the emergency room immediately. Additionally, if you have unexplained fever, a history of cancer, severe trauma, or unexplained weight loss, you need to see a doctor.

Q3. Should I get an MRI as soon as the pain starts?

Most of the time, that's not necessary. Acute back pain without a specific cause usually improves on its own within 4 to 6 weeks. If there are no red flags mentioned earlier, experts say there's no need to rush into expensive imaging tests right from the start.

Q4. What is the scientifically proven 'first treatment'?

Surprisingly simple. The key is not to just lie down because you're in pain, but to keep moving as much as possible, engage in exercises or physical therapy to restore function, and learn properly about your pain. Medications can include non-steroidal anti-inflammatory drugs (NSAIDs) when necessary, while opioid painkillers should really be a last resort.

Q5. What should I do if the pain becomes chronic?

At this point, a more comprehensive approach is needed. Personalized exercise therapy, psychological approaches like cognitive behavioral therapy, and multidisciplinary care managed by various specialists are recommended. The World Health Organization (WHO) emphasizes prioritizing non-surgical management such as exercise, education, and psychological therapy.

The phrase 'my back hurts' is rarely an experience that leaves us suddenly powerless. It's like hitting the brakes on everything we used to do without a second thought just yesterday. Back pain can feel like a huge event that disrupts not only our physical well-being but also our plans, moods, and life as a whole. However, amidst all the information, it's easy to get lost. We may wonder what we should do right away, whether we need to go to the hospital, or if we should just lie down. In this article, we will carefully outline the first things we need to check and practice in the midst of that confusion.

Is My Back Okay? Assessing Safety First

When your back hurts, the first thing you need to do is determine whether it’s a dangerous situation. This is known as looking for 'red flags.' Most back pain is not serious, but there are rare cases that could indicate an emergency.

Go to the hospital if you experience these! (Red Flags)

If you have any of the following symptoms, stop searching online and go to the hospital immediately.

  • Bladder/Bowel Issues: Recently, you suddenly have trouble controlling your bladder or bowels.
  • Abnormal Sensation: You feel numbness or strange sensations around your buttocks or saddle area.
  • Severe Weakness: You feel increasing weakness or numbness in your legs.
  • Other Red Flags: Unexplained fever, a history of cancer, recent severe trauma (like a fall), unexplained weight loss, or nighttime pain that doesn’t improve even with rest.

Episode: The Terrifying Experience of Freelance Designer Ji-hoon Park

Freelance designer Ji-hoon Park felt excruciating pain in his back when he stood up from his chair while working overnight. He thought resting for a few days would help, but the pain worsened and he started to feel numbness in his toes. Fearing that moving would make things worse, he finally went to the hospital, where the doctor surprisingly told him, "There are no red flags, so don’t worry, and you should start walking a little." Within two days of cautiously starting to walk, he experienced a significant reduction in pain.

If there are no red flags, what should you do next?

The Best Back Pain Treatments According to Science

Surprisingly, the best treatments identified by numerous studies are not injections or medications. It's about using our bodies wisely.

Type of Treatment Key Points
1st Choice: Education and Exercise It's important to learn the causes of pain and to keep moving within your limits rather than avoiding activity. Personalized exercise is most effective for chronic pain.
2nd Choice: Non-Drug Treatments Heat therapy, manual therapy, and acupuncture can help temporarily alleviate acute pain. It's even better when combined with exercise.
3rd Choice: Medication When pain is severe, you might consider using NSAIDs 'short-term' as prescribed by a doctor. Opioid painkillers should really be a last resort due to the risk of dependence.
Special Cases: Surgery/Injections This should not be considered from the start. It's only applicable for specific patients with serious nerve issues or those for whom other treatments have been ineffective.

Episode: The Transformation of Office Worker Soo-hyun Choi Through Consistency

Office worker Soo-hyun Choi, who always struggled with back pain, was disappointed by the MRI results. The doctor said, "There’s nothing special shown in the images." Frustrated that there was no clear cause for her pain, she followed her physical therapist's advice and began doing core exercises (McGill 3) for 10 minutes every day. After a month, then two months... with consistent exercise, the frequency and intensity of her pain significantly decreased, and now she enjoys weekend hikes without pain.

So what can you start doing at home today?

7-Day Recovery Plan to Start at Home (Example)

When acute back pain strikes, consider the following plan to cautiously resume activity. Of course, if your pain worsens, you should stop immediately!

  • Days 1-2: Walk briefly (10-15 minutes) 2-3 times a day. Apply a warm compress to the painful area for about 20 minutes. If the pain is severe, you can consider taking NSAIDs for a short time after consulting with a doctor or pharmacist.
  • Days 3-4: Try very light core exercises (like bird-dog, modified side plank) for about 10 minutes. Don’t overdo it.
  • Days 5-7: Increase your walking time to 20-30 minutes and slowly practice everyday movements like sitting and standing up or lifting light objects to regain confidence in your body.

Common Misunderstandings About Back Pain (FAQ)

Q. Isn't lying down for several days the best solution for back pain?

No, that's an old belief. The current consensus in the medical community is to 'maintain daily activities as much as possible.' Excessive bed rest can actually slow down recovery.

Q. My MRI showed a herniated disc. Does that mean I'll be in pain for life?

Not at all. It's very common for people who do not experience back pain to also show herniated discs or degenerative changes on an MRI. Imaging results do not always correlate with actual pain, so don't be too alarmed.

Q. Aren't injections or surgery the quickest solutions?

Not for most patients. Except in exceptional cases where there are red flags or serious nerve damage, non-surgical treatments like exercise and lifestyle modifications should be prioritized. These can be much safer and provide long-term solutions.
