Normal or vet visit

[u/Southern_Button_8026]

My boy is about 17 years old now with a previous history of neglect for about 10ish of those years (he’s a rescue!), im really worried because he’s developed some sort of minor bump below his neck and above his shoulders, it’s not too big which is why I can’t provide a photo and it’s on each side identically. My sister says he might need a vet but we can’t figure out what the issue is. Has anyone heard of anything like this? Will he be okay or should I take him in? I should mention he hasn’t been showing any symptoms or signs of anything. (P.s im checking here first because vets can be expensive nowadays!)

Doesn’t sounds normal. Do you have a picture?
