I don't drink regularly but when I do go out to drink I always get an amerreto sour. Like I did the other night it was one drink and on the way home I got this horrible ache pain in my chest and my shoulders and back. I had to lay my seat back and put my arms over my head BC its happened before and its the only thing that seems to help. I don't know what it is I haven't been to the doctor for myself BC I have no insurance but Iknow i have bad anxiety. The ache has happened before but it even though I don't drink regularly it hurt more that time than any other time. What should I do? What's the ache?
