I got a burn from a silencer, and a bubble formed with pus coming out. The thin skin layer has peeled off, and now the inner skin is pink and painful. What can I do to treat this and ease the pain?

Sounds like you have a second-degree burn with signs of infection. To help with the pain and prevent infection, you can clean the area gently with mild soap and water, then apply an antibiotic ointment like Neosporin. Cover the burn with a sterile gauze bandage to protect it. You can take over-the-counter pain relievers like ibuprofen to help with the pain and inflammation. Make sure to keep the area clean and dry, and monitor for any signs of increasing redness, swelling, or drainage, which may indicate a worsening infection. If the symptoms worsen or do not improve, please seek medical attention.
