Bump,

My injury was 4/12/14. Sometime in July I went outside and commenced hitting on some metal fence posts with a sledge hammer to see if I could jar them loose to remove them, they were in concrete.

I felt my head do something and I was not good for a good while after that, I further suspect that is possibly the reason I am having problems still.

Be patient and test the waters easy on more vigorous activities is my advice.

Bud
