question: Hi, my best friends mom has been to the ER 3 days in a row and my friend is freaking out, can you tell me what might be wrong? Here are the symptoms. The first time she had pressure on her chest and she thought she might be having a heart attack, it wasn t. But she does have an irregular heart beat yesterday she had a really high blood pressure, and today she said she had a pressure in her leg and was feeling light headed.
