Weird feeling in chest?

Last night i began to have this cold feeling in my chest. I have had it for about a day and its not painfull. It feels like someone is blowing in your chest. I have been having indegestion for about 3 days and was told to take gas x. I have taken it and the indegestion is still somewhat there. Could this be acid reflex or something esle? and what is this cold feeling in my chest?
