👉 Oxyesthesia is a condition where a person experiences intense, tingling or burning sensations in their fingertips, nails, and lips when they touch hot objects. This can be caused by certain types of burns or heat stroke, but it's also possible to develop this sensation from other sources such as trauma or infection. The exact cause of oxyesthesia is not fully understood, but it's often associated with the body experiencing a high level of physical activity during an intense heat exposure.
