The Timeline was composed from several sources, one of which is from noted regency romance author Candace Hern. Additional resources such as the Chronology of Culture, What Happened When and The timetables of history have been used to supply over six thousand entries.
Bruising around the mouth and nose area is quite common after injections. I always tell my patients to avoid aspirin, alcohol, NSAIDs, herbals (G's: Ginkgo, Garlic, Ginseng) at least one week before treatment. If a bruise develops, it usually takes about a week to resolve.
1 Two days after a bruise develops, apply a heat pack or wash cloth soaked in warm water to the area several times a day to promote healing.  Pain and tenderness should get better within a few days and the bruise should go away within a couple of weeks.
