What is the cause for the development of painful marks on finger skin after wearing a ring?

Hi doctor,

There was a mark on my finger skin due to wearing a ring. It has been seven days since that mark is being spread, and a little painful as well. Initially, it was a small mark, but now it is getting wider on that finger. I feel itching on that place sometimes. I find little water also coming from that area on the skin. I have been using Neosporin ointment on that for the last few days. It gets a little better, but again the same problem happens. I have attached an image of the finger for your reference. This skin mark is not present anywhere else. I am a housewife, and I have to do cooking and dishwashing regularly. I think the skin mark is not curing due to frequent water, handwash, and detergent use. These are some queries that I need your help with. What is the exact problem with the finger skin? Which ointment or medicine will you suggest in this case? How much time will it take to completely cure? Kindly give your opinion.
