I have mouth blisters. On lower lips frequency of recurring is fast. In mouth some other place also it happens but frequency and size both are less compare to lower lip. They start growing and burst within 24 hours. Lower lip size grows till 1-2 cm. They are usually painless but lower lip sometime pains when it grows. They are transparent and with sometime small red dot within. Lower lip now after bursting sometime skin will come out and will pain. Please let me know whom to consult.
