Yellowish/white scabbing around outer edges of abrasion wound is part of normal healing process.Serous fluid coming out of wound gets dried up and is causing this yellowish scabbing.
Your wound is not infected as there is no discharge of pus.Continue treatment and regular cleaning and dressing of wound.Get booster dose of tetanus
if not taken in last 5-10 years.It may take 7-10 days for complete healing.
You can take anti-inflammatory agents like voveran
, emanzen-d for pain and rapid healing.
Consult your doctor if you get fever
,pus discharge from wound.
Hope this could help you.
Wish you good health.
