Welcome to Health caremagic forum, Tonsilitis
may be acute or chronic infection. It usually manifest as throat pain and enlarged or swollen tonsil with pain on swallowing. But as you said you got only swollen tonsil and no pain so less likely to be an infection. As you noted pus point on tonsil, it may be a white patch
may be of keratosis
or a tonsilar cyst , which are non infective . But if persit for some more time than let an ENT specialist
examine your throat and tonsil . Avoid judging your disease on seeing mirror.
