Bumps on his tail :(

i have had my ball python for about a month, and he has two little bumps near the end of his tail. and the one on the left looks like its infected.
At first i thought he maybe just cut his tail but now i dunno.
help me!

Can you get pictures? I don't think any of us could really tell you what they are without seeing his tail. :(

I'm guessing those are his anal spurs.
