I have had back, chest and stomach pains for awhile now. I will get stabbing pains in my back and stomach. I get lightheaded, dizzy and have blurred vision often to the point I cannot see. I also have fainted before. I have terrible headaches and sometimes I cannot even move my back. I have difficulty breathing also and it hurts so bad to breathe. I have trouble walking sometimes. Heart disease, multiple sclerosis, and hypertension are in my family's background. I am 5'5, 140pounds, female, age 21 years old if that helps. I have had three children vaginally and with epidurals. No problems with any of my pregnancies.
