Of course it's ultimately your decision what you decide. Leftover human prescription antibiotics work just fine for chickens. Friends know to let me have their leftovers when they are finished with them. They sure do come in handy.
An antibiotic would be practical if you believe an infection is contributing to the lesion under discussion. In your poking and squeezing of the lesion, have you ever gotten any watery fluid or thick, cheesy substance out of it? Have you attempted to make a small incision and then put pressure on it to see what, if anything comes out? Also, note the smell of the contents of the lesion since bacteria will often have a foul odor.
