How to get rid of headaches

I am currently battling a brain tumor, so when I have a headache, I just take the painkiller used for brain tumors.

It becomes completely gone, but I don't really know what medication it is.

The effect seems really good. I don't know the name of the medicine because it's too long.

Anyway, I treat my headaches with very strong medication. I'm sorry it doesn't help much.

I was writing when I was somewhat sane, so I think this is about it.

The nurse isn't coming well today, so I'm secretly writing this late.
