6 Signs Acute Pain Is Becoming Chronic — and How to Stop It

From backaches or arthritis to a twisted ankle or swollen joint after surgery, pain is something we all have to deal with at one time or another. Acute pain (aka short-term pain) is a signal that your body’s beginning to heal itself, and in most cases, it’s temporary. But for some people, acute pain can stick around and become more long-lasting pain. “The clinical definition of chronic pain is pain lasting longer than three months or beyond expected tissue healing,” says Nicole Matar, MD, an interventional pain and spine physician at Hospital for Special Surgery in Stamford, Connecticut.
How you manage acute pain and what kind of pain you have in the first place can play a role in your risk of developing chronic pain. For instance, you might be more likely to experience chronic aches if you put off treating short-term pain.
And certain types of pain, such as pain involving nerves, tend to be tricky to alleviate and more likely to turn chronic. “Neuropathic pain, when there’s a direct injury to the nervous system, tends to be a little bit more difficult to treat,” says Connor O’Donovan, DPT, who treats people in the pain management center at the Shirley Ryan AbilityLab in Chicago. “That could be something like carpal tunnel syndrome, where your median nerve is getting compressed, or pain from a stroke or spinal cord injury.”
Similarly, certain habits and risk factors can set you up for being more prone to ongoing pain. “There are a couple of known risk factors that are very modifiable: Smoking increases rates of chronic pain, and having an unhealthy [body mass index] makes you more likely to have chronic pain,” says O’Donovan. On the flip side, exercising regularly cuts the chance that acute pain will become chronic.
What Happens in the Body When Acute Pain Becomes Chronic
“If pain is persistent, it begins to oversensitize the central nervous system,” says Dr. Matar. This sensitization of the central nervous system can occur with any type of pain and also lead to other symptoms that may seem unrelated to the pain, such as sensitivity to light or noises.
Signs of pain becoming chronic include:
1. Pain That Lasts Longer Than Expected
“Within a week or two, if it’s not progressively getting better week to week, day-to-day, then you want to reach out to your provider and get checked out,” says O’Donovan. “You should be following a fairly linear recovery from acute pain.” Recovery doesn’t have to be perfect, but the overall trend should be forward.
2. Severe Pain
Pain that’s out of proportion to what might be expected for the injury is a sign of chronic pain, says Matar. So is feeling more sensitive to touch that typically wouldn’t be painful, such as a light tap causing significant discomfort. When the nervous system becomes hypersensitive, even mild stimuli can feel intense.
3. Fatigue During the Day or Tossing and Turning at Night
Pain and sleep have a two-way relationship. Ongoing discomfort can make it hard to fall or stay asleep, and poor sleep can amplify pain signals. If you’re waking up frequently because of pain or feeling exhausted even after a full night in bed, that disruption can be a clue that pain is becoming more persistent.
4. Pain That Spreads Beyond the Original Injury Area
Spreading pain is another sign that you may be transitioning to chronic pain. “Typically, as things get more and more chronic, the pain becomes more diffuse and widespread,” says O’Donovan. For instance, rather than pain pinpointed on the front of your knee, the entire knee might ache. “That’s emblematic of how your brain is processing the input as affecting a larger area.”
5. An Increased Reliance on Pain Meds
That could mean upping your dosage of current pain meds or turning to new options, and, unfortunately, you might still struggle to find relief. “With chronic pain, patients may rely more heavily on medication without meaningful improvement,” says Matar. That may be especially true if you’ve been taking opioids for the pain. “Chronic opioid use specifically may result in opioid induced hyperalgesia, which essentially means sensitivity can worsen over time,” she says.
6. Pain That Starts Affecting Your Mood, Focus, or Daily Life
When pain lingers, it doesn’t always stay physical. You might notice you’re more irritable, anxious about another injury, or avoiding activities you used to enjoy. When discomfort begins to shape your behavior, emotions, or routines, it can be a sign the issue has moved beyond a short-term injury.
How to Prevent Pain From Turning Chronic
If you have acute pain, prioritize your recovery, especially by focusing on getting adequate sleep every night and managing any stress, Matar suggests. And while you should take things easy as you recover, remember that not using the affected area at all may not be the right move. “Obviously, you’ll want to follow your provider’s recommendations, but generally speaking, early mobilization is being shown more and more to be beneficial for treating pain,” says O’Donovan.
The Takeaway
- A little soreness after an illness, injury, or surgery is normal, but you should see gradual improvement of acute pain. If pain lingers beyond the expected healing window, isn’t improving week to week, or starts spreading, that’s your cue to check in with a healthcare provider, rather than pushing through it.
- Over time, persistent pain can rewire how your brain and spinal cord process signals, which is why it can feel more intense, be more widespread, or be triggered by light touch.
- Prioritize stress management, sleep, and gentle movement and follow through with treatments, such as physical therapy, to lower the risk of acute pain turning chronic.
