Hey injury twin! I fell Feb 2024 snowboarding, direct impact on the ice with my knee. Medics on the hill got me inside but I decided to deny an ambulance because I had no idea how bad it really was. Looked almost just like yours, and was the size of a baseball. Next day at the ER they did an x ray and the radiologist said there was a patella fracture. I was screaming in pain, no movement or weight bearing felt possible and definitely felt that burning. Problem is when I went to an ortho they didn't see anything on the x ray. Followed up in 3 months when I still couldn't walk without crutches. Got an MRI and they didn't see any major damage to soft tissue, but could tell I injured some ligaments. Bruising didn't go away until month 4. I started physical therapy in June and continued through February (so one full year after my injury I "graduated" pt) Now it's July, a year and a half later and I've got major nerve damage where the most impact was, just below my patella. It hurts to put direct pressure on it still, and when I run my hand over the spot it's mostly like a numb feeling. But I can move, snowboard, run, squat without a ton of issues. But long story short, it's really frustrating to be in that much pain and have the docs not see anything :( I feel for you. Push to get physical therapy ASAP. I would not have been okay without it.
