I had surgery November 20 for squamous cell carcinoma on my right cheek. Two weeks ago, it became infected and found a small hairlike substance in the wound and was treated with Keflex. Today, found wound infected again and went to the doctor. They cultured wound, guessing now is MRSA, and gave me Antibiotics. Now, found letter in mail saying my doctor wants new labs as my kidney function showed concern. This is the second time post surgery, my kidneys showed something high (I forgot what) after surgery. I am 48. I am an athlete and health care professional. You may speak in medical terms. Thank you.
