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 didnt.  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.
Hi, Welcome to Chat Doctor, Best treatment for staphylococcal infection for you is combination of Chat Doctor. For tingling and itching you can take oral antihistamines and can apply topical antibacterial agents over the affected area. If you are getting these symptoms more frequently you may have to consult your dermatologist for confirming diagnosis and to take proper treatment. Thank you.
