Gosh, Eddie I can't see THIS Mri causing all those symptoms. You might want to get an MRI of your cervical spine (neck) and see if that is where your problem lies. The neck can effect the arms and hands a great deal, so perhaps that is where it's coming from.
Also, the light-headedness should be considered too, so ask your doc for the cervical Mri. Hopefully he'll agree and go ahead and do it. I hope so. If he does, post it here again and we can help you out. Best of luck and God bless. Hugs, Lee
