I had a head injury, however since that I have only 30% strength in my right hand.  I was hit by a vehicle while I was directing traffic and landed on my back and busted the back of the head open.  I had no bleeding on the brain.  Just concussion and pain in the neck on the right side.  I have tried PT, but no help. I am a 50 yo white male.  I am on warfarin with A-fib.
Hello! Welcome on Chat Doctor ! I would like to directly review your brain MRI study for a more professional opinion. Considering the neck pain, it is also necessary to perform a cervical spine MRI, to exclude any possible disk herniation in this region. Physiotherapy is the main treatment in such case. In case of a bulging disc, surgery may be a possible treatment choice. Hope you will find this answer helpful! Best regards,
