Hi- I have an infected thumb, where the side of my nail meets the skin. There is no open wound. It is not an ingrown nail. It is VERY tender, a bit swollen, warm and a tinge of yellowish color where the brunt of the pain is located. Since there is no opening wound, I m not sure if I can self treat this. Anything over the counter you d recommend, or do I need to see a doctor? Would my GP be the doctor to call? Thank you in advance. Patti Meihls
