Hi, I am a 52 year old female and currently I am having pain in left leg from right above knee down leg into the foot. It feels as if I m wearing a bandage ( but I m not), there is swelling in the knee, some in the leg area, foot has a tight feeling. There isn t any redness nor hotness. Strangely, even my arm pit area on the left side is swollen and painful. This started two days ago from no known injury. At times I feel like I can t take a full breath.
