Neck injuries are common in accidents and not always reported. I suggest you consult a neurosurgeon and get examined for possible neck injury
. The neck pain
after an injury usually intensifies the next day, when the muscles get swollen and may go in to spasm. Your doctor may ask you to get cervical spine
x rays and MRI scan if whiplash injury
is suspected. If there is any significant injury, they may prescribe a neck collar for you. Please follow instructions given to you. Flying should to be a problem if the injury is mild. However significant injury cannot be ruled out without clinical examination and imaging. If you have numbness
in finger tips then please inform your doctor about it. You may apply anti inflammatory medications and muscle relaxants.
Hope this helps
