What was the hit area of your original concussion?
A side hit, back of head, frontal, or top downward?
How did it happen? Car accident, a fall/falling object, something hit you, ect?


Some of the symptoms you mention (nerve pain, weak right thigh, left arm aches and other symptoms. This developed into aches in my middle hand and the side of my hands to my feet and not my right arm. ) could be unrelated, a general check up might be good , don't assume all symptoms are concussion related.. Especially new symptoms..


Depending on your age & overall health, things start to accumulate...
Also consider if any close relatives have any neuro/muscular conditions.
