Hi I am Wondering how to differentiate a cold sore or a pimple on my chin , 2 small sore itchy bumps , started with one thought it was 2 small pimples and I picked one wet fluid came out and dried to large , to me , scab , don t know how to treat it if I cant tell what it is ??? I used bacitraycin last night and today cultivate steroid cream. what happens if I treat area with abreva ?? I have only had fever blisters / cold sores on lips when sick , sun , upset stomach never chin , I will send photo. thank you jina I am on disability and that is a shame you have to make a profit off everything , I am poor so therefore you can not help me???? I am not surprised just ANOTHER SCAM ON THE INTERNET! you wasted a lot of my time and made me think you were actually going to help me!!!! How can you refund something I DO NOT have?? I am on disability , how do you think I can PAY for a simple question??????
