you have a slight tremor
, probably from the stress
from the accident. It is unlikely, my friend, that you have a serious neurological condition. Most likely your symptoms will go way in a few days and do not medical attention at this time. If tremor continues, eliminate caffeine and decongestants, which may worsen it, and try to avoid excessive alcohol, which will make it temporarily better but of course is unsafe to your body to do habitually or chronically. have a good day and the less you focus on it, the more likely it will go away.
