a 16 years old girl problem

The girl is my niece , and since her first month she had many troubles

mainly about her heart.

She had surgery regarding that years later. The thing is before three

years she began to complain from a little swelling in her both feet. Also,

her two legs seem weak.


Her mother and I took her to many doctors and hospitals, and she found a

good treatment in one of them.

The girl remained three years fine, living her life normally, she can walk,

play and cook.


Now, the problem came again . Her left leg muscle ( the calf I think ) is

having this swollen now, and the right leg knee is painful with a bit of

swollen also.

I'm taking her to a private hospital next Saturday.
