I found a tree with tons of pointed bumps on the trunk with small thorns on the ends. I was wondering what type of tree it was. It was pretty tall and the bumps were at longest about 2 inches, it was alive too.enter image description here

    Good question & illustration, and helpful comment; if could include an overall illustration, an illustration of the top, a close illustration of the leaves, overall height, trunk diameter, soil type, and if the tree is growing in a wet, medium or fairly dry location, could also be helpful. We encourage you to browse through the Help center to learn more about how the site works! Thank you! Welcome to the site!

As I mentioned in another answer recently, this looks like Zanthoxylum clava-herculis to me based on the distinctive look and region (Louisiana) that you mentioned. It's also known as the Hercules' club, pepperwood, or southern prickly ash:

Most likely Ceiba speciosa, commonly known as Silk Floss tree, native to parts of South America - the trunk is green when the tree is young and is capable of photosynthesis when the leaves are not present. The trunk often has a bulbous base, though this feature is not always particularly pronounced. https://en.m.wikipedia.org/wiki/Ceiba_speciosa
