At : At your age an average blood pressure would be around 121/80. The low end of normal would be about 109/76 and the high end of normal would be 133/84. So one issue is that your blood pressure reading is on the low side.You pulse rate sounds fine. If you weigh 90 pounds and you are 5 feet and one inches tall - you are underweight. A normal weight for that height would be 105 pounds + or - 10%. I do not know if you are feeling acutely ill or if this is how you always feel. I don't know if this is your normal blood pressure or not, or if this was a one time value. I can not tell you the reason for the signs and symptoms that you have shared: are you dehydrated, are you malnourished, do you have a virus? I suggest that you discuss this with your doctor.
