A cut in right pinky knuckle that is spreading like a rash
Patient: I've gotten a cut in my right pinky knuckle and I'm not sure how I got it.  Now it is a day later and it has a rash and is spreading down my pinky and across my hand.  Do you know what it is or what is causing it? The spot where the rash/cut is, is very dry and cracking and painful to touch. Doctor: 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 an infection at the site of previous trauma. We can try conservative treatment first but if the condition continues to worsen , then you might need to consult a physician. 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. Keep hand elevated esp at night in order to prevent any swelling. Oral antibiotics are required if the cellulitis increases, which a dermatologist / physician can examine and suggest .Take care, Wishing you speedy recovery, Dr Geetika Paul MD ( Dermatology)
