“A red streak climbing your calf after a puncture in the yard is lymphangitis, and the fact that it is still spreading after three days means your body is not handling this on its own. I would get it looked at today, before you travel, because an infection that is advancing up your leg rarely waits for a convenient time.”

“A red streak moving up your leg three days after a puncture is lymphangitis, and waiting for it to fade is not the call I would make. I would get it checked before the trip; a foot puncture with spreading redness can turn into a deeper infection fast, and you do not want to be on a plane or in a hotel when it does.”

“A red streak climbing the calf three days after a puncture is lymphangitis until proven otherwise, and waiting for it to fade is the wrong bet. I would get it looked at before the trip; the cost of an urgent care visit beats a hospital admission in another city.”

“I once got bit by a centipede in my own yard and watched the redness spread about 15 cm across my leg. I told myself the same thing, that it would calm down tomorrow, but a streak climbing your calf is not the kind of thing you wait out before a work trip. Get it looked at today.”
