My mom's knee surgery

Well, my mom had her knee surgery done this past Wednesday. When she called me she sounded just fine, but she said that she was really starting to feel some pains once the medicine started to disappear from her system. She was in so much pain yesterday that she could not even talk on the phone. She finally called this morning and said that her knee has been swollen (according to the Dr. which is normal for few days) and she can't wait to go back to her own house. Yes, she is staying with her friend, but she said that she can be more comfortable at her own home. I feel so bad for not be able to help her out. I hope that her recovery will be a quick one. My brother will be helping her out this weekend, so I feel a little better but I really want to be by her side right now to help her out!
