Hello and thanks for the query
The pain is due to the soft tissue injury
at the site or may be due to infection in the collected blood at the site. Infection can only be present if you have fever
or raised local area temperature. To get rid from the problem take analgesic
and anti-inflammatory drug to reduce pain and swelling. In case of infection antibiotic is needed.
Wear a elastic bandage
at the site.
Do hot and cold
fermentation at least twice a day.
Local application of analgesic gel can be helpful.
Keep the part elevated as much as you can.
Go for X-ray if symptoms does not resolve in 3-4 days.
Hope this will help you.
