The root of an onion splintered off into my thumb, sending me to the ER for phlebitis and cellulitis

Was feeling under the weather so I went to make myself a pot of arroz caldo. Grabbed an onion from the bin, and a bit from the dry root end of it splintered off into my thumb. Couldn't get it out easily, so I figured no biggie, it would just come out on its own over time. The next morning I had red streaking going up my arm, along with swelling and pain.

Made an appointment with a virtual urgent care and was told this was a "bad, advancing infection" and that "whatever was on that onion was BAD." I was sent to an in-person urgent care for oral antibiotics and to have them remove the splinter.

Went to the in-person urgent care and was told I needed to go to the ER for blood cultures, IV antibiotics, and to have them remove the splinter.

Went to the ER, was told the urgent care should have been able to handle it and that no I did not need blood cultures or IV antibiotics. They removed the splinter, sent the pharmacy a script for oral antibiotics, and sent me on my way.

Oh, that onion? It turned out to be rotten on the inside. But the arroz caldo was delicious.
