I don’t know what kind of insect bites hard lumps very itchy, considering that it may be the manifestation of insect bite dermatitis, the patient can improve the condition through symptomatic treatment, medication, surgical treatment and other ways. 1. Symptomatic treatment: after being stung by a bee, the stinger should be removed immediately and the venom should be squeezed out, and then rinsed with water, and local ice or cold wet compresses should be used; ticks should not be forcibly removed from the skin when they bite, and ether or local anesthetics can be used to apply on the head of the tick in order to take out the insect body. Alkaline soap and water can also be used to wash the affected area to relieve itching. 2. Drug treatment: patients can use topical drugs under the guidance of doctors, such as compound flumethasone ointment, glycerine lotion and so on for local treatment, or oral antihistamines, such as loratadine, cetirizine and so on; severe cases can be short-term use of glucocorticosteroids, such as prednisone and so on for systemic treatment. 3. Surgical treatment: After being bitten by ticks, if the mouthpiece remains in the skin, it can be removed through surgery after local anesthesia to reduce itching and swelling. It is recommended that patients strictly follow the doctor’s instructions for medication, actively cooperate with the doctor’s treatment, pay attention to monitoring the condition in life, and consult the doctor in time if there is any abnormality.
