The pain from injections for keloid scars is due to the stimulation of nerve endings in the skin and subcutaneous tissue during the injection process.
The pain during injections for keloids primarily stems from the physical stimulation during the injection process. Keloids are overgrown scar tissues, often larger than the original wound. When injected, this tissue is directly stimulated by the medication or treatment substance, activating pain receptors in the skin and subcutaneous tissue. These receptors transmit pain signals to the brain, causing the patient to feel pain. The blood vessel and nerve distribution in keloids may differ from normal skin, making the pain more pronounced during injection. Inflammation at the injection site can also exacerbate the pain, as inflammatory mediators further activate the pain receptors.
When treating keloids, patients may encounter various treatment options, including injections of corticosteroids, 5-fluorouracil, and interferon. While these medications can inhibit keloid growth, pain during the injection process is unavoidable. The effectiveness of keloid treatment is often closely related to individual patient differences, the timing of treatment, and post-treatment care. Before undergoing treatment, patients need to communicate fully with their doctors, understand the potential discomfort during the process, and be psychologically prepared.
[Management Tip:]
1. Communicate fully with your doctor before the injection to understand the possible discomfort caused by the treatment.
2. Pay attention to local care after injection to avoid infection.
3. Have regular follow-up visits to monitor changes in the keloid scars.
