50 year old male patient, drinker, smoker 1pack/2day, works as a beekeper, presents with urticaria (nodules type) around the skin of the head, neck and thigh. Says that has got these symptoms for over 3 months. The rash only appears in the morning, and retracts after. Blood culture, biochemistry, all is normal. No pruritus or fever associated with.
On the stool exam, giardia came out, however, after 7 days of metronidazole, no improvement. The other morning, his left eye got swollen, like Tyson's after 12 rounds. :eek:
What other exams can he perform? Immunogram? Any other ideas? anything is welcomed...:confused:
