my mother was in the garden today. She has had heart rouble in the past and she says that she is shaking. She is considering going to the hospital but is waiting to see if it will stop. Could this be from over exposure from the sun and humidity?
Hello, Regarding your concern, I would explain that her symptoms could be related to low blood pressure, due to deny Chat Doctor.  Other possible causes to consider would be an infection and fever. Does she have a fever? Anyway, I would recommend going to the ER for a careful physical exam and some tests (a resting ECG, blood electrolytes, fasting glucose, complete blood count). Hope I have answered your query. Let me know if I can assist you further. Take care
