<s>[INST] I have a spot on my chest that I originally thought was acne, but now it has some discoloration and if you squeeze it some really rank smelling pus comes out. It is only one spot and it is about the size of a dime maybe smaller. What is this and is there a remedy? [/INST] Is there any itching or pain on the area. it May be just an infection of the sweat or sebaceous glands. if u have diabetes just have a routine checkup and maintain the level. when the pustule is ripe, just remove the pus and clean it with dettol and apply a paste of Turmeric and neem leaves. it Will heal quickly. </s>
