This question is answered by the Deputy Chief Physician Li Xiaolin from the Emergency Department at Ganzhou People's Hospital, contracted through PureHealth. How long does it take for swelling to subside after a burn? The duration depends on individual constitution and the measures taken after the burn. It also greatly relates to usual diet and other factors. If the burn is mild and not very obvious, it can be resolved relatively quickly with standard treatment. However, if the burn is severe and covers a large area, and if swelling is also significant, the swelling is relatively difficult to reduce and will take a longer time to subside. Inappropriate treatment can lead to worsening of the condition and further complications. Therefore, immediate measures should be taken when a burn occurs: - Rinse with cold water for at least half an hour or until the pain subsides mainly. - Thoroughly disinfect with iodine to alleviate symptoms and slow the progression of the condition. Additionally, be cautious with your diet by avoiding spicy and stimulating foods, seafood, and inflammatory foods. For free expert consultation, please search PureHealth.
