Yes, wind can indeed be trapped that high. Some even feel it up in their chest. Have you tried drinking any teas or tried OTC gas meds? When I get that pain and pressure really high, I try to drink fennel or mint tea, and I walk. Walking helps dislodge the wind, and those teas help break up the gas.
BTW - Do you have acid reflux or a hernia? Those could also cause similar pain.
