7 months ago a open sore came up on my bottom lip and it was sensitive to spicy or acidy food. This went on for 4 month. I went to the dermatologist, took a biopsy that came back as a staph infection. I was told due to precancerous cell cause a sore which got infected. I took antibotics the sore did go away but the rawness around my lips and sensitiveness didn't. On top of that now the outside of my chin keeps itching and my lip continues to get crusty and sore, The last week both of my lips are tingling and numb.
