I'd lay off the golf clubs for a while. The twisting while trying to keep your head still would not be good right now. Another exercise you might try if you have access to a pool. Swimming. The breast stroke is great for shoulder rehab. Pull back and pinch your shoulder blades together and down. The suspension in the water can be easy on a back.

Before you return to road work, get some foam ear plugs. Run with them to see how much pounding your foot plant causes. You will be surprised. Then, try to soften your foot plants. When the upper neck is traumatized, the up and down pounding can be aggravating.
