Whether or not an ant bite will heal on its own depends on the type of ant. If it is a common ant that basically does not secrete toxins, it can usually heal itself; if it is an ant that can secrete stronger toxins, such as the red fire ant, it may not heal itself. Common ant bites usually cause redness and swelling of the skin mainly due to anthranilic acid, which may be accompanied by mild burning pain and itching. For the redness and swelling caused by common ant bites, soapy water and alkaline water can be used to flush the area, because ant acid is acidic, and alkaline liquid can neutralize the ant acid, so that the redness and swelling, pain and itching can be relieved as soon as possible. If you are bitten by red fire ants, the symptoms will be relatively severe because red fire ants can secrete toxins and the human body can have an allergic reaction to the toxin proteins, which can not only manifest as redness, swelling, pain and itching at the bite site, but also cause systemic reactions, which can manifest as dizziness, palpitations, and in severe cases, high fever and shock, or even life-threatening. Because of the seriousness of the disease, the symptoms can be extended from local to systemic, so generally need to go to the hospital in a timely manner, local can be given furnace glycerin lotion to reduce the symptoms of itching, redness can be applied dexamethasone cream, systemic medication can be given to anti-allergic drug therapy, such as loratadine, cetirizine, etc., if necessary, glucocorticoids can be given for treatment.
