I am prone to this cold sores and even have one now about three days ago i noticed a small bump on the left side of my tongue it is not painful i was just wondering if it could be a cold sore spread into my tongue or my health anxiety makes me think it's

Not a cold sore: Cold sores occur on the outside of the mouth/borders of lips, not in the mouth and are caused by the herpes virus. Canker sores, which are not caused by the herpes virus occur in the mouth, and are typically painful. This could just be an enlarged tongue papilla, which is common and not a problem. Have your doctor check it to be sure.
