Over the past 2 or 3 weeks I’ve noticed a small, sensitive spot on my lower leg, near the shin. It didn’t/doesn’t hurt, but if I touched it it felt slightly sensitive, it was a new and different condition, and I didn’t know what it was. It wasn’t bothersome enough to do anything about it, such as visit a doctor, but I’ve been puzzled by it.
Then in the past couple of days I realized it’s apparently been swelling, so that now there appears to be a bubble of fluid beneath the skin, in the quadrant between the front and the side, a few inches below the knee. The bubble is not hugely distended so that passersby on the street would notice it, and it’s not dark purple, but upon close examination I can see there is a bubble and if poke gently I can tell it appears to be about 2 inches wide and 4 inches long (tall) and is puffy (ie., full of fluid). This morning I stood up from the couch and without thinking put my hand directly on it, applying pressure, and it was a little painful.
So, of course, I’m trying to figure what it is, what caused it, and how it will go away.
My best guess is I caused it from running or cycling, maybe something like a shin splint, an internal injury that’s causing blood or pus or some other fluid to keep building up where it doesn’t belong. I don’t run regularly, but I did a few weeks ago, and I go for a long bike ride every weekend. I’ve had shin splints before, when I used to jog, and I recall them hurting like hell (which this doesn’t) and I don’t recall them causing a swollen bump, so I’m doubtful that’s exactly it, but I don’t know what else it might be.
Any ideas? Sports exertion (but not sudden impact injury) leading to mild hematoma (I think that must be the right word). Seems too late to ice it to make it go away, and lancing it is too extreme. Nor do I want to stop cycling. But it appears to be growing rather than shrinking. :eh:
