Hello,I have been having recurrent itchy truncal rash that appears to be urticarial for the past year. After onset, I noticed parotid swelling. This is my fifth episode. I have seen a PCP, dermatologist, and ENT specialist. Recent CBC shows 50 eosinophils, otherwise WNL. Titers are WNL. ENT consult suspected dehydration as a cause of the swelling, because I usually have associated tiredness and thirst from emotional and physical stressors being in medical school. Dermatologist suspects viral exanthem or drug allergy. I noticed hives related to cold for the past 2 years, however the parotid swelling is new this year. What do you think I may have? I feel my condition is probably chronic, virally related, triggered by stress/dehydration.
Hello and welcome to Chat Doctor, Do you have any history of taking any medicines that may cause the truncate rash ? The rise in eosinophil points towards urticaria. Focal infection is a well documented cause of urticaria and it is may be due to infection in your carotids, you may be getting this. Once the infection is out of the system, maybe you'll get better. Or else it can certainly be that you are allergic to some Chat Doctor. Take oral antiallergicslike cetirizine/ loratadine and see the response. Hope I helped.
