Is it possible it's "just a bruise"? With a lump on a bruise on the shin like that, it should be kind of painful to push on it.
Is he having any symptoms? Lyme rashes can show up looking more like a bruise on some people, particularly if they have darker skin - unlike me, I could blind someone in bright light!!
I would watch for symptoms and keep a close eye on that "bruise". You can give him Astragalus as a precaution if you wish. Buhner suggests using it for early infections and for preventing Lyme. I've been using it all this year.
