In general, scarring is usually referred to as keloids. Keloid pain may be caused by inflammation and irritation of nerves. 1. Inflammation: keloid is a more specific type of benign tumor, in the inflammatory or reactive stage, there are more blood vessels and inflammatory cells infiltrated in the scar tissue. Due to the stimulation of inflammatory cells and inflammatory factors, the keloid will have the symptom of pain, especially touch pain and spontaneous pain, and in severe cases, it even makes people unable to sleep. 2. Stimulation of nerves: mainly caused by the local hypoxic environment stimulating the nerve endings, patients will experience congestion and scar hyperplasia during wound healing. During this period, a large amount of collagen will be synthesized in the scar site, which will aggravate the pain of pathological scarring, and thus the symptom of keloid pain will occur. In addition, patients are advised to go to the hospital in time when keloid pain occurs to avoid delaying the condition.
