What are these large bumps and holes on my potatoes?

First, the bumps. A few of the potatoes I literally just dug up have these large bumps on them. What are they? Boy, I hope it's safe to eat, cuz I just did!

Now for the holes. I dug this one up, and there was a small worm curled up in one of these holes on one end of the potato! Ew! But, it doesn't look like the holes go all the way through - do you think it's safe to cut this end off and eat the rest?

In this pic, I tried to get the worm out with my shovel...kinda mashed up the potato.

Here is the other side of the potato. I rinsed off the potato, but there is still dirt in the holes.

The knobs and bumps are normal.

Describe the worm. I'm thinking it maybe wireworm. If they are wireworm, you could try mixing a little used coffee grounds into the soil next year.

I would just cut off the end with holes and eat the rest.

I guess they don't sell knobby and bumpy ones at the supermarket? Cuz I've never seen it before. I was hoping someone would reassure me it was normal! I guess they just use "pretty" ones at the supermarket. I've never grown potatoes before, so I have absolutely no clue what I'm doing right or wrong. Or what's diseased or not.

The worm was like a small, skinny, like inch or so long dark blackish, pinkish color, slimy looking. I don't know, it all happened so fast, when I saw it, I yelped and started hitting it with my digging tool trying to get it out.

Yes, I hate bugs. If you guys only knew how petrified I was of bugs, especially spiders, you would be so proud of me heading into my jungle of a garden every day.
