Does blisters on face & elbow with hyper nature suggest allergic reaction?
Patient: My son had an endoscopy yesterday.  They are checking for celiac disease.  He developed these blisters on his right elbow and a few on his face.  The ones on his face are gone but the ones on his elbow are still there and they look just like fever blisters.  He is also acting pretty hyper.  This is how he usually gets when he's had something he is allergic to.  Should I be concerned? Doctor: HI, thanks for using healthcare magicIf these are the symptoms that you would normally observe when he has an allergic response then you may want to consider giving him an anti histamine.These are available over the counter.Eg benadryl, , zyrtec, claritine, allegraI hope this helps
