Hello!
Thank you for asking on HCM!
In my opinion the rash on her hand is not related to the head
concussion. It may be indicative of a subcutaneous
hematoma, probably related to a trauma in this region.
If she has pain in her hand, a hand X ray study may be necessary.
But, I do not think there is any need to go to the ER now.
I would just advise some rest and avoid any
head trauma in the next weeks. If her situation does not improve or even worsens (strong headache, nausea,
dizziness, confusion), I would recommend bringing her immediately to the ER for a new brain CT scan to exclude delayed
subdural hemorrhage.
Hope to have been helpful to you!
Wishing all the best, Dr. Aida
