My 17 year old daughter has been a great kid her whole life, we have open and honest communitcation, also we get along great. These last couple of months she has been experiancing alot of exhaustion, causing her to lose focus in her school work, which she is a senior in high school, before was very motivated for school, now if she can get the energy to go to school she does, otherwise she is in bed, or when she can go out and get some socialization, she comes home before curfew. For a couple of weeks she had alot of crying spells and sever depression moments, after they occured we took her to the doctor and put her on medication; thinking it would help with the exhaustion, crying, socialization, and depression. She is now on cymbalta, before trying this one she was on prozac. In the last month, she hasn't cried at all, she seems to have no emotion, she's sleeping more when she doesn't want to, and when she wants to do something she doesn't get any sleep causing her not to be able to go out. Back pain has been a problem, she has scoliosis already, but in her lower back and its very minor, she has been complaining of back pain only on the right side of her body, where her rib cage is. We have tried popping her back and massaging it, but she is saying that its inside of her ribs not outside. When doing normal activities, like walking in and out of a building, and around the house, outside to her car, which is not far, she becomes severly out of breath and has to take a moment to catch it, and her heart rate starts racing. Everytime she takes a deep breath, she says she feels a pain were her back is hurting, I have noticed that when she is breathing normally its small breaths, not complete breaths. She has been tapping alot as well. When shes sitting on the couch she cant sit still alway tapping her feet or rocking back and fourth. After starting her medication, she has lost weight, going from 120 to 109 in two months. When it comes to urination she has no problem but her urine is constantly a different color every time, sometimes its light, then sometimes its really dark. Before I took her to the doctor I had her write all of her symptoms down, so we went to an urgent care in our town the first visit, he only pressed on her back three times, then gave her very strong muscle relaxers, which did nothing but make her drunk feeling. So I took her back again, the nurse practitioner who always sees her came in and we gave her the symptoms list, she thought it could have been a blood clot in her lung because our family has a genetic disease called antiphospholipid syndrome, which makes our blood clot more than normal. But, my daughter has never been diagnosed with it, so the nurse examined my daughter, saying her oxygen levels were at a 96, which is low for a teen who isnt obese and doesnt smoke. The nurse ordered a chest xray and blood test. They both came out fine according to the nurse. We are having her tested for the syndrome. But, my daughter is still in pain. Could it be something really serious that we are overlooking? Please help, she wants to go back to being a normal teen, and senior. Thanks so much.
