Last night I was checking myself out and I realized I had a single hard bump on my right lip. It is only the size of an average pimple but when I quizzed it nothing came out but clear liquid. It hurt and it doesn't seem like an ingrown hair. I put a warm compress on it last night and in the morning I squeezed it and blood came out, but it looks glossy on tip and not willing to pop. I then got in a warm bath and soaked then put antibiotic ointment on it and a bandaid. It has seemed to go down, but still concerned. I had unprotected sex a few days ago, but I hadn't had sex in almost a year and also he had a longtime monogamous girlfriend before me. It hurts but not sure if its because I messed with it or not.
