i have a tightness across my chest ones,like above my boobs going upto my neck.its not further down where i usualy get it when im nervous.this is different.my friend said she has had this and the doctor prescribed anti histamines(not sure on spelling)because it said it can mean a little allergy to something and hers cleared up.any how im sitting worried about it.has anyone else had this and i know this isnt the usual tight chest caused by anxiety.x
