Thanks for the query.
In the first episode you developed a reaction to the deo.
Some people tend to develop allergy
when a similar product is used or even to unreleated products.
You need to take treatment with topical steroids
Dont worry it is not lymphoma
Lymphoma doesnt present with just recurrant itch .
Please meet a dermatologist
and discuss regarding this.
Let me know if you have any other doubt.
you can ask a direct question to me on this forum, following the below link.
Wishing you a good health.
