I banded a 600# calf 5 days ago. He got a tetanus shot earlier and then a booster at banding. Yesterday the scrotum was swollen, the skin near the band looks infected. Temp was 103.6. Gave him banamine & Pen G, sprayed on topical treatment. Today 2nd Pen G, temp 102. Still swollen & soar. Plan on at least 2 more days on Pen G. Will he come along or should I get the vet?
