I just figured it was due to the heat we have been having. It appears to go away pretty quickly. She was in the hospital last Tuesday for her jaw and they checked her heart and I told them that this was happening but they said her heart was ok. The problem is that she says it and then when its gone she does not remember it happening. She got up this afternoon and was very wobbly and came out to the dining room and the electricity had been turned off for 30 minutes and it was stifling and then the a/c came on and she said it again and then she forgot about it again. I am so overwhelmed that everyday its something different and she is not faking it at all. But she hates that I would call life alert so I am not sure she is pretending she is ok. Anyone else have this problem? I hope this made sense, oh and she has been up only for 2.5 hours and said that she was going to fall asleep again. The doctor prescribed her a low dose of xanax and my sister wants me to give her some and I not going to do that, especially since she wants to go back to sleep! Thanks
