I can understand your concern.
Since you have had a trauma and after this trauma, the complains have started, it's necessary for you to undergo a full neurological work up.
Some nerve may be damaged due to the trauma which needs to be ruled out.
Kindly consult a orthopedic and spice surgeon in person or a neurosurgeon in person for further evaluation and treatment.
Certain radiological investigations will be required.
Kindly don't delay this and go as soon as possible.
Dr. Anil Kumar Jain.
