A few years ago I had a pinched nerve in the c6/c7. Pain, numb left hand first 2 fingers etc. 8 weeks of drugs, PT in a traction device (heaven!!!!), preceded by heat and electro stimulation. That helped out with the major pain and numbness but I still get the tingling and tightness.
I looked around and found a air traction device for the neck. Here is a link to one similiar to the one I have

I heat the neck up with a heating pad designed for the neck ~15 min. Then about 10 - 15 reps with the air device. Works like a charm! I can feel the tingling/pain disappear imediatly and saves me on the getting to PT and doctors visits. I do it about 3 times a week or when my neck reminds me that I have gotten off sched. Good luck to ya.
