Raised bump on right inner cheek wall.

This is parotid duct opening which is a major salivary gland. The fluid was filled into the cavity as there is secretion of saliva whenever you eat something especially spicy or sour. That fluid which filled up was actually your saliva! The duct here in the pictures seems inflammed but if it isn't causing you any trouble then just let it be. However, at times you may bite over it. You don't need to do anything as such. If it is concerning you a lot or if it enlarges, just get evaluated for a duct calculi.

If asymptomatic you don't need to worry or take any action. Just let it be and forget about it.

Hello! This is due to a cheek bite while eating food. Nothing to worry about.

Don't Chew food very fast. Chew it with medium pace. This will help you to prevent accidentally cheek biting while eating. 

Hello This is due to cheek bite

The small bump you see on the inner side of your right cheek after consuming spicy foods could be a mucocele. Mucoceles are harmless cyst-like structures that form when a salivary gland duct gets blocked or damaged, causing saliva to accumulate and create a fluid-filled bump. Typically, mucoceles resolve on their own within a few weeks without the need for treatment. However, since you mentioned that the bump has changed and now appears as a red bump without fluid, it would be wise to seek advice from a healthcare professional or a dentist to get an accurate diagnosis. While it’s difficult to provide a definitive assessment without a professional examination, there are a few possibilities to consider. The red bump could be an inflamed or irritated mucocele, or it might be a different condition altogether. It’s best to have it evaluated to rule out any potential concerns. In the meantime, you can try to avoid further irritation by refraining from consuming spicy or acidic foods that may aggravate the area. Maintaining good oral hygiene, such as brushing gently and regularly, can also help prevent infection and promote healing. Remember, seeking professional medical advice is crucial to receive an accurate diagnosis and appropriate treatment, if needed.
