Fingertip Amputated Questions

Patient: I have a amputated fingertip I have been changing and cleaning it everyday. It happened on April 20th and it has been looking like this for a week and a half. I would also like to mention I take vitamins A, C, and Zinc everyday. So my questions are can I stop changing it, is it ok to go swimming, and is it still healing because its still missing a good bit of skin please get back to me and let me know what you think.

Symptoms: None
