Hello.
Thanks for writing to us.
It is the collection of the blood due to the
injury which is causing all these symptoms. This collection of blood is likely to resolve on its own if it is not infected. An
MRI scan of the area will help in confirming the diagnosis.
I hope this information has been both informative and helpful for you.
Regards,
Dr. Praveen Tayal
