This can be allergy to aspirin
.But since this has failed to relieve after benadryl
, I think other cause of such swelling should also be ruled out.
Periorbital edema/swelling can be a common presenting symptom of kidney issue.I guess you need a primary clinical evaluation , so consider seeing your doctor.
Mean while try cetirizine
, that might help if its allergy.And if doctor feels it's allergy then more aggressive with steroids
can be planned, if needed.
