Hi, I had a minor cut in the back of my knee due to a stainless steel scale cut. To stop the blood, I used an expired dettol and bandaged it. But on the second day of the injury, I undressed the wound and it had healed. Then I took some antibiotics, painkiller, and paracetamol and also a tt injection. When I tried to straighten my leg, I realised I cannot and I am having swelling and pain in my calf and back of the knee. I thought it was because of the wound but the wound healed on the third day. But the pain in the calf still persists and I can not straighten my leg, neither can I put it on ground, and I can not even move my ankle up and down. I even got blood sugar tested which came out to be 112. Whats the issue I am facing and how can I treat it? Please help me! thanks in advance!
