Yesterday I was diagnosed with acute paronychia of my right middle finger by my primary care physician. I had a gel manicure the day before and the pain began that night after I went to bed. The pain kept me up most of the night. I was given a prescription for cephalexin 500 mg and have taken 4 doses so far. My finger hurts very much and the area around and under the nail and at the fingertip has turned purple and is very swollen. It was swollen and red yesterday and very, very painful, but no purple color. Should I go to an ER or should I wait until tomorrow to get an appointment with my family doctor? Is this normal in the progression of this condition? I currently take 40 mg Atorvastatin and 800 mg 3x per day for back pain/sciatica. Thank you for your help!
