Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'гиперчувствительность' (general hypersensitivity). The correct clinical term is 'гипералгезия'.
- Do not confuse with 'аллергия' (allergy).
Common Mistakes
- Mispronouncing the 'g' as hard /g/ instead of soft /dʒ/.
- Misspelling as 'hyperalgia' or 'hyperalgesic' (which is the adjective).

FAQ
Frequently Asked Questions
Hyperalgesia is an increased pain response to a stimulus that is normally painful. Allodynia is pain caused by a stimulus that does not normally provoke pain (like light touch).
No, it is a symptom or a clinical sign of an underlying condition, such as nerve injury, inflammation, or certain diseases like fibromyalgia.
Treatment focuses on the underlying cause. Management may involve medications (like certain antidepressants or anticonvulsants), physical therapy, and addressing central sensitisation mechanisms.
It is common in specific patient populations with chronic pain conditions, post-surgical pain, or neuropathies, but it is not a common experience for the general healthy population.
