Hi, Thank you very much for your question. Generally, fainting appears after any finger cut or seeing blood is mostly related with stress and anxiety. If her doctor will diagnose it as general anxiety, counseling or psychotherapy, physiotherapy, treating related stress and avoidance of triggering factors by doing meditations or yoga can be helpful in recovering from the condition. Hope this information proves helpful to you. Take Care & Regards!!!
She is most likely having some sort of seizure activity, which can cause a person to pass out, and most definitely is causing her to kick around so hard that she's bruising herself. You should tell her to go to her doctor and discuss her symptoms, and he should refer her to a neurologist who can do a full workup on her and he can give her medcines to control the fainting and muscle spasming. This is not something to fool around with, and since it's so easy to control, there's no reason why she shouldn't go to the doc. Also, epilepsy can be a dangerous illness if left untreated, she might have a fainting spell and seizure whilst driving a car or walking along a busy street and so forth. Also, if she does not have epilepsy, then at the very least her doc needs to find out why she's fainting so much, because that can indicate a heart or circulatory problem of some kind, or could even be because of some medication she's already on for some other health issue. I hope this helps you and your daughter out. Keep us posted.
