My husband (68 yrs old) bent his knees squatting all the way to the floor a week ago... knew he stretched them too far afterwards. Couple of days ago, he felt his knee "extend" too much just walking in the house. We are thinking it's a hyper-extended hamstring tendon. Yesterday, we noticed the back of the leg at the knee... about 2 in. above the bend, and in the bend, and about 1/3 way down the calf is bruised & is slightly swelled. How should this be treated?
Will appreciate any advice on this.
