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.
Small bruises usually go away in a couple of days but big ones can take up to a couple of weeks. It all depends on how hard the impact was on the area of your body, and if the bruise is on a large muscular area or on bone. It depends how big and dark the bruise is. Small bruises go away in two-three days for me.
