Fell off a scooter- onto a previously damaged leg , just around knee area, below the knee. Last injury 4 weeks with swelling going down and then this one on top of previous injury is very sore , very swollen leg , leg hot to touch on the shin area just around knee. Tight but not numb like previous injury,Injury happened 5 days ago. Had scan for veins after last injury -it was all ok. Do I just need to wait it out?
