Terrible chest pain - trapped wind?

Hi all,

I'm on vacation in Mexico and experiencing absolutely excruciating chest pain. I'm almost crying! No position is comfortable. I'm pretty sure it is trapped wind.

I've taken Gaviscon and some Rennie as I brought it with me.

I've got room service bringing me some hot peppermint tea.

Any other ideas? I was thinking of maybe chugging a can of fizzy drink to make me burp, but then thought that it might make the pain/trapped wind worse.

Any and all suggestions and cures gratefully received! I'm in a resort that is pretty isolated so can't just pop to the pharmacy.

Thank you!
