Should I take to GP or try to douse it with disinfectants (hydrogen perioxide)? It's red with a scab, clearly swollen, had it about 10 days but hasn't spread to other toes. We thought it was a blister & have been slow to do anything. Just doused it with H2O2 and it went all bubbling so reckon it must be an infection.
Sensitive to touch but don't think it otherwise bothers her.
