Like two weeks ago, I had a random wound on my knee, and regularly applied ointment which disinfects the area (Levomekol). I once accidentally scraped off a scab, and fresh wound was under there, which I cleaned and applied ointment again. Now there is swelling, and currently, I cannot put any weight on this knee, and it hurts. Did you guys have dealt with this kind of injuries? I am losing my mind here, thinking it's a tendon/tissue infection.
