I need to find out how can i take care of my fingers after surgery. left hand- ring finger: tip amputation, index finger has a 180 cut. should i leave the index covered? how often should i change dressing on the ring finger?

Ask your surgeon : Your question is a very good one, but because only your surgeon knows what he/she has performed, the post op needs will be related to that. Discuss with your surgeon to get exact needs. In general, rest and keeping the areas clean are in order, but specific antibiotic ointments/creams, splinting devices, occupational therapy, wrapping techniques are all specific to your needs. This is important!
