Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
Last night a bump came up in my top lip, over a matter of minutes. It has grown bigger since last night and there is what appears to be yellow pus in it now. It is also painful. I have had cold sores in the past however this is different to how they normally are. Could there be any other causes other than a cold sore?
Many thanks
