Although they could be lymph nodes, kind of odd they are exactly the same size. Can you feel any lumps in the groin area or neck?

Just went back and reread first post, 5 yrs old. You say 'he' but from pics, looks like a female to me. Don't know anything about this type of squirrel but the area the lumps are is making me think something to do with mammory glands.
I'm pretty sure this is a male squirrel as he used to have swollen testicles a few years back and was quite shocked too!

The lumps are soft and squishy, no other lumps felt in other areas.
