My wife had gunshot piercing done one month back at a jweller shop. soon after the piercing she developed pain and redness at the site hence we removed the jwellery and put some turmeric and mustard oil at the site. but instead of drying and healing the site has started generating puss and is painful to put anything in the piercing. and oinment/ medications or precautions we can take to heal better would be great. thanks in advance.
