Thanks for posting your query to HCM.
It seems from your query that your are suffering from the problem of "Infected Lipoma".Lipomas
are fatty tissue collection under the skin. Generally the only problem felt by the patient is the size of lipoma and the compression symptoms some time if it is over some pressure area.
As per your problem the lipoma got bursted up by itself and now still is discharging red and white substance.
I recommend and suggest you to meet the doctor immediately because lipoma are not able to extrude out from the body by itself and there are always chances of secondary infection if it is partially remaining in the body.
So it is best advised to seek a medical help
at the earliest. In between kindly do not pinch, pop or squeeze the area by yourself as can lead to more infection of the area.
Hope these informations are helpful.
"Wish you good health"
