<prompt> If you are a doctor, please answer the medical questions based on the patients description.I started exercising last week because the doctor said that it would help my blood pressure which was running 244 over 142. I have been ill for the past 4 years and was put on a lot of medication including high doses of prednizone so my weight plummeted from 110 lbs. to 189 lbs. so I was wanting to lose weight and tone up along with reducing my blood pressure, so this morning I decided to hurry up the weight loss and before I started exercising I took 2 Lipozenes and 1 MetaboUp. I just got through doing my exercises about 30 minutes ago and for the first time after doing them I m having a lot of problems breathing, swalling, talking and my it hurts when I do try to take a breath along with my heart racing really fast. Could you please tell me what s going on with me? I m scared to death right now.  <response>: Hello! Welcome on Chat Doctor! I carefully passed through your question and would recommend going to the ER for a careful check-up. The fact that you have difficulty breathing, chest pain, with tachycardia could be related to a cardiac arrhythmia or myocardial ischemia. I recommend going to the ER for the above tests: - a resting ECG and cardiac enzymes- a chest X-ray study-some blood lab tests complete blood count, blood electrolytes, fasting glucose. Hope you will find this answer helpful! Kind regards,
