[|Human|] I hit the dead center of my knee cap about as hard as you could imagine hitting it against the edge of a metal door frame at work. I can barely walk, my knee is swollen and hot to touch and pain is unbearable in my knee when I bend or unbend my leg.What could I have done?
[|AI|]  Dear Friend. I am Chat Doctor. I understand your concern. I would advise you to follow :1. A painkiller with anti-inflammatory action like Tab Synapse D twice a day for 5 days.2. Voting gel locally 3-4 times a day3. Hot fomentation. I suppose you will get relief by this. But a X-ray / MRI is advisable to see for any fracture / ligament tear. If you have any further query, you may please ask me. Stay Healthy
