I had surgery on my toe for a peronychia a week ago. It was doing great until 3 days ago when I switched from a gauze dressing to a CVS brand bandaid. It began itching a little on that day and the itching got worse the next day. I stopped using the bandaid and went back to a gauze bandage thinking perhaps I am allergic to the bandaid materials. But the itching has gotten worse....I mean unbearable especially at night and has spread to the toes on either side of the one that had the surgery. The surgical incision is healing nicely but this itching is making the toe swell again some.
