I was diagnosed with diabetes in 2000 and it has been 10 years since then. I have been taking insulin injections since ’05. I don’t know why I have been having this problem, but I often have abdominal injections, and I am careful to rotate the sites. However, I don’t know why I feel pain in some places and not in others when I have injections in my stomach. Since insulin is usually injected subcutaneously, the pain caused by insulin injection also becomes a reason for patients to refuse insulin. How to reduce the pain caused by insulin injection to patients, the following 8 issues are what sugar lovers need to pay attention to. 1, insulin to room temperature before injection: insulin from the refrigerator after the best put to room temperature before injection. Otherwise, injecting insulin just taken out of the refrigerator will cause pain to the patient after injection due to low temperature. 2. Choose a fine and sharp needle: choosing a fine and sharp injection needle for subcutaneous injection is an important means to reduce the pain of injection. Patients are advised to choose special insulin syringes, whose needles are fine and sharp, and the pain during injection is less than that of ordinary medical 1 ml syringes. 3, wait for the alcohol to evaporate before injection: if the alcohol used to disinfect the skin is not evaporated before injection, the alcohol is brought under the skin from the eye of the needle, which can also cause pain. 4, hand pinch skin traction injection: when injecting, use one hand to gently pinch up the skin of the injection site about 3 cm wide and cause 5, into the needle to be decisive: for patients who have just started using insulin, due to fear of pain, often into the needle is not decisive. Don’t change the direction when pulling out the needle: After the injection is completed, keep the original direction of the needle and pull out the needle quickly so as to minimize the stimulation of the needle on the subcutaneous nerve endings. 7. Relax mentally and physically: During the whole injection process, try to stay relaxed so as to avoid the increased pain sensitivity caused by excessive concentration. 8. Change the injection site: Change the injection site regularly. The injection site should be kept at a distance of 3 to 4 cm from the last injection site each time, avoiding skin infections and subcutaneous hard nodes, which can reduce pain as much as possible.
