Uneven forearm size question

[Zeigo]

I have had several injuries to my left wrist, hand, shoulder and neck, which has caused my left forearm to become 1.5 inches small then my right.
To even them out is it better to work both at same time or just do forearm exercises to the left side for a few month to even the size out???

THANKS for any advise !!!

i would try to do some isolated work over there if its that much smaller than the other
