Question: I have two tiny lumps under my skin on my forearm after a fall a month ago. It radiates a bit upwards one doctor says two hives one says fatty deposits. They are smaller than a pea on top one another. Both said not to worry. Can it be from trauma from the fall? I am scared.

Brief Answer:
harmless swelling

Detailed Answer:
Hi XXXX...
Welcome to healthcare magic.
The bumps on forearms if appeared immediately after trauma then they are most likely fat necrosis or hematoma.
If they are present before injury then they may be lipoma or neurofibromas again no serious matter.
In either case no need to worry.
These swellings may look bad but they never turn dangerous.
I hope the advise will be helpful for you.

Thank you. They came about 3 weeks after trauma. A dumb fall at home

It's me again. I can move the small of the lumps up and down and even into the slightly larger one which is half the size of a pea. I'm scared. Two doctors said not cancer. Do I just forget about it?

no serious issue

Detailed Answer:
Welcome back.
They are fat collections due to injury.
They will reduce in size during time to come but will stay.
Take care.
