Hematoma

Detailed Answer:
Hi, thanks for using Healthcaremagic.

I went through your query and understood your concerns.


Your symptoms are suggestive if hematoma ( collection of blood in muscular layer) It takes longer time to resolve. At your stage slow exercise to thumb and warm compression do help to resolve swelling. ultrasound treatment also helps to reduce swelling.

If there are any changes on overlying skin, it needs to be examined for infection. In that case needs antibiotic treatment.

Hope I answered your query. Feel free to ask further related query.

Hello. I fell and hit my head exactly 2 weeks ago, resulting in a pretty large hematoma. For the most part it has gone away, with just some minor bruising and a small hard lump about the size of a pea left. It is still pretty tender to touch. I've had some minor headaches the last couple of weeks, but no dizziness or loss of conscoiusness. This morning I woke up with a sharp pain in my forehead that lasted about 2 hours, then slowly went away. Do I need to be checked out or is this normal healing for this type of injury?

Hi,

I fell a month ago and have a large hard hematoma just below and joining my knee. I have had Xrays, nothing broken, I went to an Orthopedic who diagnosed it as a hematoma. What can I do to reduce the size? Is there any danger of blood clots? Thanks
