Hi there.
The fact that the lesion started on the same day as the pedicure could be incidental or coincidental!
Please get a
skin biopsy done if dermatologists' have already treated you with antifungals & no relief recieved.
The skin biopsy & histopathology report will be conclusive.
This will not affect your
pregnancy status. It could just be a dry eczematous patch.
Alternatively, you could try using a topical steroid-antibiotic cream for a week & see the results together with a good moisturiser. But do remember this will modify the picture & a subsequent biopsy will be redundant!
Hope have guided you in the right direction as best online as possible.
Wish you a quick recovery & a safe delivery. Please do visit a dermatologist when time permits. Cheerz!
