I woke up last night feeling as if I might have some gas pain...under my right rib cage and thru to my back. It was very uncomfortable. I have a history of PEs so I always fear that, but I wasn t having a shortness of breath, instead it felt as if something was catching when I tried to take a full breath. After a lot of rest it is a little better today, but still hurting. Any thoughts? I am not vomiting, not feverish or fatigued (any more than usual life fatigue). Thank you.
