Hi ,  Thanks for the query.  I completely understand your concern and I hope I am able to help you for the same.  Looks like you have developed cellulitis over the umbilical region.  We can try conservative treatment first but if the condition continues to worsen , then you might need to consult a dermatologist.  Avoid touching it too much.  Avoid using any kind of cold dreams or oils, as it might increase the lesion . You can start using any topical antibiotic/antiseptic cream(like mupirocin cream) over the lesion for 2-3 days . Take some pain killers along for relieving the associated pain and discomfort.  Oral antibiotics are required if the cellulitis increases, which a dermatologist can examine and suggest . Take care,  Wishing you speedy recovery,  Dr Geetika Paul  MD ( Dermatology)
