I am a 62 year old woman who has developed this pain or discomfort in my central chest (between my breasts.) It began about a week ago and the best way I can describe it is that it kind of feels like an ice cream headache. It starts mild and gets more severe; lasting about a minute or two, then goes away for several minutes and then begins again. I have several episodes a day. I can't really tell if it's in my esophagus or in my chest. Any suggestions?
