Today, I cut my hand with a knife. Will it be inflamed when the weather is hot? What should I do?

According to what you said, if the hand skin is hot after being cut by a sharp instrument, the possibility of inflammation and infection cannot be ruled out.

Suggestion:

It is suggested that patients should first pay attention to keeping local skin wounds clean to avoid secondary infection when the wounds meet water. At the same time, we should go to the hospital for surgical treatment in time and actively carry out debridement and suture treatment. If the wound is serious, it is best to take antibiotics orally according to the doctor's advice to prevent infection. Pay attention to avoid spicy food as much as possible in life, and follow up regularly to review dressing changes.
