Brief Answer:
Attributed to
delayed hypersensitivity reaction
Detailed Answer:
Hello,
Thanks for your query.
Based on your case history, the symptoms can be attributed to delayed hypersensitivity reaction.
The itch & swelling in your left wrist was either due to an
allergic reaction to an allergen or insect bite during the camping trip, which was relieved by an anti allergy medication (
benadryl).
But the appearance of similar lesions in right wrist indicates a delayed response to the allergen.
Though symptomatic relief can be obtained with antihistamine preparation like Allegra & corticosteroid like
Prednisolone, the underlying cause needs to be treated.
So, kindly
consult a Dermatologist and get a proper clinical examination done, including an Allergen test.
Once the causative allergen is identified, specific management step can be taken against it.
There is no need to worry, you will be fine.
Wishing you a good health.
Please let me know if I need to clarify further.
Take care.
