In the past few days, the cold air has come again, and I believe that many friends should take all kinds of cold protection measures in order to resist this cold wave, such as baking fires, stoves, warm babies, electric blankets, warm water bags, etc.
For example, a few days ago, a patient ** came to the department and developed such a rash on her calf.
When asked if she had been in contact with the stove or other similar items that were too hot for a long time, she said that she had this (the weather has been cold recently, around the end of January 2024, and she had to be close to the stove for a long time for heating and work), so it was obvious that this was a sign of "fire red spots".
Improper heating methods, the woman suffered from fire erythema
"Erythema on fire" is a kind of problem caused by long-term thermal stimulation, which is more common in people who use fires, hot water bottles, stoves, and electric blankets for heating for a long time (so it is more common in middle-aged and elderly people), or people who need long-term physiotherapy, wax therapy, and diathermy due to other diseases, as well as people who work under high temperature conditions.
Reticular telangiectasia and pigmentation appear on the ** of the long-term hot parts (mostly seen in the inner thighs, extensor calves, chest and back, abdomen, etc.), and there are generally no symptoms of self-discomfort, and there may only be a slight grid of erythema in the early stage, if the time of this warm stimulation is prolonged, the color of the erythema will deepen and darken.
Therefore, when the weather is cold, in order to keep warm, you can use various cold protection measures appropriately, but you should also pay attention to avoid long-term exposure to these warm stimuli locally, pay attention to adjust the temperature and distance, move your limbs regularly, and usually pay attention to observe whether there are abnormal changes.
Generally speaking, these "grid-like erythema" will gradually subside when leaving this "local long-term high temperature" environment, and if there is a local "pigmentation" left, you can go to the local hospital ** department for treatment.
