Thanks for writing to us.
From the description it seems, you could be having contact irritant dermatitis
in the area of neosporin
application.. Firstly stop neosporin application.To help your wound heal take an oral antibiotic, apply steroid antibiotic cream. To reduce itchiness take oral cetirizine
and to reduce pain and swelling you may take Brufen. Also keep your legs at slightly elevated position. Sometimes if irritant dermatitis is severe, a short course of oral steroid might be required. I would advise that you meet your dermatologist
for diagnosis and treatment.
Hope this helped.
