I have a raw cut/blister on my foot (on the ankle bone) from new tennis shoes that rubbed and cut into my skin during a long tennis match. It is red around the edges and painful and it s been 3 days and seems to be getting worse instead of better. I ve been using hydrogen peroxide to clean it and collidial silver oitment but it s still red and painful and oozing a little. Should I go see a doctor for a possible infection?
Good day, and thanks for your question. You have what is called a Friction blister. Well, It's likely to be infected. Please stop the use of HY Chat Doctor.  Use Acetaminophen 1g 3 times daily for pain, use Erythromycin tablets 500\u00a0mg 4 times daily. Check your blood sugar level to know whether you are diabetic and if you are diabetic please kindly go to the hospital for proper check up. You can continue the use of the ointment. Hope it helps. Thank you.
