Referred pain is when you feel pain near the site of the actual problem, and referred hyperalgesia means that this pain is more intense. It happens because the area where you feel the pain shares nerve connections with the area that actually has the problem. Hyperalgesia and allodynia are related issues that the irrational mind of addicts and alcoholics are very similar, but there’s one key difference. With hyperalgesia, you feel more pain in response to things that are supposed to hurt. With allodynia, you feel pain in response to things that shouldn’t hurt. You should call your provider right away if allodynia comes on suddenly or is very painful.
- Increased sensitivity usually starts when something causes irritation to a particular organ system.
- If there’s an underlying problem in the brain or spinal cord, your doctor will assess and treat this accordingly.
- While some may resolve with the management of the underlying cause, some cases of hyperesthesia tend to be chronic and require long-term treatment.
- The most common types of hyperesthesia are allodynia, which involves experiencing pain from a stimulus that does not typically cause pain, and hyperalgesia, an extreme response to a painful stimulus.
- During periods of extreme pain, some people may even have suicidal thoughts.

A multidisciplinary approach that is able to provide timely diagnosis and treatment has the best outcomes. This activity outlines the evaluation and management of hyperesthesia and reviews the role of the interprofessional team in evaluating and treating patients with this condition. Secondary hyperalgesia is characterized by hyperalgesia to mechanical but not heat stimuli. Two distinct forms of mechanical adderall and cardiovascular risk hyperalgesia have been reported (Figure 14). Punctate hyperalgesia (or static hyperalgesia) is characterized by hyperalgesia to sharp stimuli that normally cause pain (e.g., stiff von Frey probes and pin prick). Stroking hyperalgesia (or dynamic hyperalgesia or allodynia) is characterized by pain to a light moving touch (e.g., stroking of the skin with a soft brush) but not blunt pressure.
Hyperesthesia vs. hyperalgesia
In addition, enhanced pain to woolen fabrics is observed in the zone of secondary hyperalgesia. Since the prickliness of woolen fabrics is encoded by activity in nociceptors, not mechanoreceptors, activity in nociceptors likely accounts for this hyperalgesia. Selective nerve blocks revealed that punctate hyperalgesia disappeared when Aδ nerve fibers were blocked, how long does ecstasy last suggesting that Aδ nociceptors are important. The primary hyperalgesia that follows injury is characterized by increased pain in response not only to heat stimuli but also to mechanical stimuli. One possible explanation for secondary hyperalgesia is that the sensitization process that occurs at the site of injury spreads to adjacent uninjured tissue.

In other words, with hyperalgesia, there is increased pain response to a painful stimulus. The most important way to treat opioid-induced hyperalgesia is to begin with a healthy respect for just how potent these medications can be. We are often aware aware of the most common and dangerous side-effects such as overdose, addiction, nausea, and constipation, but pay less attention to the other ways in which they can impact our health. It is important to use opioid pain medications only when necessary, at the lowest effective dose, and for as short a period of time as possible. Early identification of hyperesthesia and other neuropathic pain symptoms is essential to start the patient on a proper treatment plan. The education of the patient early on during the treatment is necessary to establish realistic pain goals.
Identical test heat stimuli ranging from 41 to 49°C were presented to the glabrous skin of the hand in humans and monkeys before and after a localized heat injury (53°C, 30 s stimulus). In humans, the burn led to prominent primary hyperalgesia within minutes, characterized by increased pain from both mechanical and heat stimuli. Following the burn, the heat threshold for type I AMHs in monkey was greatly decreased and the response to suprathreshold stimuli was increased.
Can I prevent neuropathic pain?
This suggests that the propensity to sensitize is a function of skin type. Whether this is due to differences in the milieu or due to differences in the properties of the neurons is not known. Hyperesthesia commonly happens along with neuropathic pain and other pain- or nerve-related conditions. Your provider’s job is to diagnose and treat conditions you have; they won’t judge what you’re experiencing or how it’s affecting your life. The goal of diagnosis and treatment is to help return your senses to how they should be working and keep them from drowning out the things you want to experience. “Visceral hyperalgesia” describes an increased sensitivity to visceral stimulation as a result of injury to, or inflammation of, an internal organ.
If you experience hyperesthesia, seeing a healthcare provider as soon as possible is important. In other words, with hyperpathia, your reaction to a stimulus, especially a repeating one, is increased. Such stimuli include touch, vibration, pinpricks, heat, cold, and pressure. Strong pain medications, like narcotics, are not used because they can slow down the digestive system and cause increased pain.
The irritation may occur after a virus, illness or injury, but sometimes there is no clear cause. Hyperalgesia is a treatable condition that may respond to standard treatment. Examining each of the potential targets will provide mechanistic insights, which may elucidate the role of neuroinflammation in both sexes, particularly with regard to shifting the timing of treatment initiation.
Opioid-induced hyperalgesia is a potential cause of hyperalgesia and must be differentiated to optimize therapeutic decision-making. Because it can be difficult to distinguish from tolerance, opioid-induced hyperalgesia is frequently treated by increasing the dosage, potentially exacerbating the problem by increasing sensitivity to pain. Long-term opioid (heroin and morphine) use can lead to hyperalgesia and pain out of proportion to physical findings, which is a common cause of the loss of efficacy of these medications over time. The properties of punctate and stroking hyperalgesia are different, suggesting that the neural mechanisms may differ. In a rat sciatic nerve constriction model of persistent neuropathic pain, males exhibited significant antihyperalgesic effects in response to a 2-week CBDA-ME regimen that were sustained long after treatment cessation.
This is usually a symptom of conditions like diabetes, shingles, fibromyalgia and migraine headaches. To relieve allodynia, your provider will treat the condition that’s causing pain. Allodynia happens when things that don’t usually cause pain feel very painful.
This condition happens because of disruptions or changes in how your nervous system processes pain. Hyperalgesia is an issue that can happen with many conditions and circumstances. Some of these are minor and will improve on their own, while others are more serious and need medical care. Instead, your brain interprets the effects, effectively translating other signals into feelings of pain.
A multidisciplinary team approach has been shown to provide the most effective and lasting results. Because there is no standard method for detecting hyperalgesia, diagnosis can be difficult. Typically, your doctor will assess your symptoms, medical history, and medications. They may conduct a physical examination to look for recent injuries or underlying diseases. Sensitization of C-fiber [7,13,22,63] and A-fiber [16,19,31] nociceptors to heat stimuli after injury has been reported and might account for the hyperalgesia to heat at the site of injury. Hyperalgesia to mechanical stimuli also occurs after a cutaneous injury and after inflammation.
