There is a large salivary gland under the tongue, in the floor of the mouth, that feels "squishy". I don't know how you can possibly "see" your tonsils as it requires special mirrors and techniques or a nasolaryngoscope that only an ENT can do. The tonsils reside in the far back of the throat sandwiched next to the side of the base of the tongue. Even dentists and hygenists cannot visualize that part of the throat. When they palpate that area on me (which requires placing a gloved finger all the way to the base of the tongue they are looking to feel something that is hard. Most oral cancers have been there for some time before thay are detected (in my case 2 years) it is unlikely that red bumps occuring suddenly would be cancerous. There are many things it could be besides cancer. Lymph nodes are supposed to swell up to fight infections and they will naturally become tender or painful. You need to take a deep breath and break the lock of fear that has settled upon you. It's been said many times here that "it ain't cancer until the pathology report says it is". It is well for you to definiteively determine the cause of your pain for your own peace of mind and an ENT or head & neck surgeon, with cancer experience, should be able to make a quick determination as to the cause.
