About 6 weeks ago I sustained a bad and bloody cut on the side of my left knee. The sutures were removed a few days too early and the wound ripped open the same day. It healed well but a very painful hard bump developed right above the scar.
When examined it feels like an inch long cylindrical object with a sharp end right under the skin. It stabs me whenever I bend my knee or put my pants on. I feel a very sharp, lingering pain on and around it when I squat or bend my knee too agressively. The formation touches the scar but the scar itself doesn't hurt at all.
It's been restricting me for about a month now, I am unable to perform some basic cleaning tasks at home and getting dressed is painful. I can't run at all, it makes me feel a sharp stabbing pain with every step. What is that thing? Should I wait for my appointment?
