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.
For a bone bruise that's visible on MRI, it usually takes at least two months for the injury to heal completely. Some bone bruises take a whole year to heal, but that's in rare cases only. You need to relax and get a lot of rest during the healing phase.
