I have pain in my right leg, behind the knee and inside. It hurts to extend it when driving, it hurts to bend over and stretch it a little to shave my leg, seems to feel like a pulling pain inside...maybe a tendon? Getting more uncomfortable daily, when I kneel on the floor, I cannot sit back on my heels...a lot of pain in the back of the leg behind the knee and inside. I can take walks with no problem but getting up and down off the floor is hard. I have an active grandson that likes me to get down on the floor to play with him. I had a Doppler ultrasound 2 days ago to rule out a blood clot or cyst (my gyn referred me for that). They could not detect anything.
