sharp neck & shoulder pain - Is form wrong??

[BeachBride]

Frequently, I get a sharp pain in the side of neck and down shoulder blade when I'm jogging on the treadmill - I usually go about 6.0 mph.

I must be doing something wrong? Am I slouching? Last night, it got so bad, I had to quit after 15-20 minutes.

You might have to see a specialist.

It might be the increased bloodflow is expanding an Artery or Capillary, which is pushing on a mildly trapped nerve perhaps.

It could be posture, but to honest, I can't really think of anything else.
