Hello Heather Seamons. Thanks for writing to us.
The lesion you mention may be due to Eczema
. You can start with application of a topical steroid
for 7 days.If it is verity itchy, you may have oral anti allergic tablets.Try to keep the area hydrated by using medicated emollients very liberally.Usually this should reduce the problem.Even after stopping the steroid application, you should continue the emollient to keep the recurrence to minimum.
In case you feel the response is inadequate, you can visit dermatologist
and confirm the diagnosis.
Hope this is helpful.Take care!
