Most haematomas get better quickly and remember to avoid massage to your injured area. Some may take longer to resolve and you might feel a raised lump for some time. After the first 48 hours and whilst you wait for it to heal, just keep gently exercising and stretching the area as long as you don't cause pain.

Should a hematoma be massaged?

Typically, a hematoma of a muscle will cure itself with rest and time.

Does massaging a hematoma help it go away?

Don't massage or rub the injury because you can break more blood vessels in the process. Instead, give yourself time for the pain and swelling to subside and apply ice immediately and as needed.
