Hi, Hope You Are Having A Great Afternoon! I Have

Hi, hope you are having a great afternoon! I have a question about a health issue my 20 year old daughter is having!
She has had two spells and I am concerned. She is 3 hours away at college and is stubborn! What has happened is, her head gets tingly and it moves down her body, her stomach starts hurting and she feels faint and loses her vision. Usually she lays down when it happens and it takes about an hour for her to be able to get up. She just feels weak and like her muscles won't work. The other day she pushed through it so she could get to class and when she came to, she was laying in the middle of her room and doesn't remember anything except she sat down, her stomach hurt really bad, she dry heaved and stood back up, everything went black, heard a crash and woke up in the middle of her room. She went into the bathroom, and evidentally she fell into the bathroom counter as everything was knocked off the counter and was on the floor!! She also has what we think are anxiety attacks but this is different. Any ideas? I cannot get her to go to a doctor!! She has also been having a lot of back pain and leg pain but not sure that is related! Thanks in advance!!
