My daughter has mono, it started January 30. Wednesday March 1st she was just walking and now she has pain in her left calf , it goes from the ankle all the way to her knee. Her calf is swollen. I took her back into the DR. yesterday, they did a blood test and said she does not have a clot, just keep it elevated and it should go away. This morning she couldn t stand on her leg. She said last night she was awoke twice with a sharp pain in her calf it lasted aprox 1-2 min. then the pain was still the same, just an ache all of the time. Made worse by walking, she said it even hurts when she touches it. any clue?
