My mom is 90yrs and sometimes she gets this warm feeling over her body and says it only lasts a few seconds, but she will feel a little weak after it happens. she takes her blood pressure when this happens and the pressure is fine. she is on 6 bloodpressure pills and a low thyroid pill. we were thinking maybe it is coming from her stomach, maybe the pills could be affecting her stomach. it doesn't happen all the time, but it hit her twice in a week. other than that she is in pretty good health. she can do everything on her own, except needs a walker. thank you
