Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead to the development of reticulated erythema , hyperpigmentation , scaling, and telangiectasias in the affected ...
Paresthesia, also known as pins and needles, is an abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause. [1] Paresthesia may be transient or chronic, and may have many possible underlying causes. [1]

Hot flashes, night sweats, and heat sensitivity can be a sign of hyperthyroidism, hormonal changes, or menopause. Here, experts share potential causes.
It is sometimes described as feeling like acid under the skin. Burning dysesthesia might accurately reflect an acidotic state in the synapses and perineural space. Some ion channels will open to a low pH , and the acid sensing ion channel has been shown to open at body temperature, in a model of nerve injury pain.
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
If the condition progresses to heat stroke, then hot, dry skin is typical [2] as blood vessels dilate in an attempt to increase heat loss. An inability to cool the body through perspiration may cause dry skin. Hyperthermia from neurological disease may include little or no sweating, cardiovascular problems, and confusion or delirium.
Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, usually from the Sun.Common symptoms in humans and other animals include red or reddish skin that is hot to the touch or painful, general fatigue, and mild dizziness.
