Ginger may be helping...I have been drinking a ginger drink I feel is helping. Someone actually described almost exactly what I do. I take about a tablespoon of chopped fresh ginger root in two cups of water that I let steep. Sometimes I put some clove, cinnamon, and honey in too. I call it my ginger tea. I also eat the ginger as well.
I have been doing some neck stretches and muscle massage to the SCM muscle over the last month as well which I feel might be beneficial.
