Recently saw several patients with paronychia. Almost all children. Almost all have the habit of sucking fingers and toes often. One of them was a child with a serious condition. Because the parents did not pay enough attention to it, he had merged with sub-abdominal abscess when he came to the clinic. It is relatively troublesome to deal with. I dealt with too many patients with paronychia, because of the lack of timely treatment, leading to cases of osteomyelitis. Therefore, we must pay attention to paronychia, especially children’s paronychia. The concept of paronychia nails and nail bed closely fit. Nail grooves are formed where the nails and skin folds meet. An infection at the paronychia is called paronychia. Subungual abscess is an infection between the nail and the nail bed. Why should I mention the subungual abscess? It is because in the clinic, the nail groove and subungual abscess can be converted to each other or exist at the same time. Symptoms of paronychia Paronychia and subungual abscess are often related to bad habits such as hand puncture, nail cutting too short, ingrown nails, and long-term finger sucking. At the beginning of the disease, there were often redness and swelling at the nail folds, which felt pain. After the disease progresses, a visually visible abscess can form in the nail groove. The pain worsened, and the redness and swelling fluctuated, with yellow-white pus spots. If it invades under the nails, it can form subungual abscesses, and even form purulent finger inflammation. The pain is severe and can cause fever and other systemic symptoms. Once treatment of paronychia is found, it needs to be given enough attention. Seek medical attention in time. If the condition is mild and no abscess is formed, oral antibacterial drugs can be taken. Topical external application of fish stone fat ointment, physical therapy. For those with abscess formation, the drainage should be cut in time. Seriously ill people even need to pull out their nails partially or completely. As far as my personal experience is concerned, it is better to cut early rather than later. Under normal circumstances, as long as the drainage is complete, it will be good to change the medicine a few times.
