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.
If the pain worsens; the pain should lessen with time. The bruise is accompanied by swelling and extreme pain, especially if you take a blood-thinning medication for a medical condition. A bruise does not improve within 2 weeks or fails to completely clear after 3 or 4 weeks.
